Hi, You are extremely lucky, I don't want to put a downer of things, but we found out the same at 8 weeks, I was over the moon, it couldn't have been better news, the family would be complete, I didn't think of twins, but ID twins, were actually a dream we didnt even know we could have, come true. Sadly it wasn't to be I didn't didnt realise I had TTTS at 19 weeks, and because the hospital didn't scan me every 2, (a patronising consultant at C&W poo poo'd my 'I am sure I am meant to be scanned every 2 weeks), and other things were missed like measuring my belly by a different consultant, we had one of our little girls pass away at 20 weeks from TTTS. TTTS is real, it says 15% but I believe it is under reported and more like 25% likely hood, so please, join this group Twin-To-Twin Transfusion Syndrome - UK Parents on Facebook, it could save your twins lives. I wish I had known about it from 8 weeks pregnant, but as 2 hospital staff told me, (which made me so angry) 'we don't want to scare mums' like we are all a bunch of idiots who don't have a right to information.
If the likely hood of dying crossing the road was 15%, I would want to have all the information to improve those odds, so please anyone reading this post, who is an ID pregnancy (TTTS only effects identical twin pregnancies) please join that group they will provide you with information on what should happen at each scan - which you should INSIST be done by a twin expert, not any old sonographer. You should 100% see a consultant every 2 weeks minimum, and you shouldn't be offered anything other than a C section (TTTS can occur at birth too).
The pain this caused me is immeasurable, I am lucky to have a surviving girl who looks like she has avoided brain damage, but because of blunders my odds of her having brain damage after we lost one were 35%, rather than 5% if you get laser in time when you find out you have TTTS, which can also save both twins.
Tamba don't send out symptom information in their pack which should be changed, so please put these symptoms on your fridge, and join the Facebook group, who happily advise what to ask what to look for and have experienced a lot of things. Everyone is more than happy for people without TTTS to be on that Facebook group, it is the best thing to have mums who are better informed, then go on to have no TTTS, but for the unlucky of us who do, at least within seconds of symptoms you will have someone who has been through what you might be experiencing and telling you what to do or ask or watch for.
Please be informed. I would book, scan 1 week, consultant the next, rather than convenience putting the 2 appointments in one day, you are meant to see a consultant every 2 wks, and a scan every 2 weeks.
Consultant appt - ask for them to measure how many weeks your belly is (I measured 31 at 20 weeks after we lost our baby, and I told the consultant, 'I feel really big', he didn't bother to measure, which could have made the difference.
If something feels wrong, don't sleep on it, go in get checked out, the hospital will be very helpful, and mention TTTS if they aren't.
If you feel big - go and get checked, pressure in your vagina, so if you are joking ' I feel like I am going to go into labour' go in get checked.
Warning signs in the mother include:
The sensation of a rapid growth of the womb
A uterus that measures large for dates
Abdominal pain or tightness, or uterine contractions
Sudden increases in body weight
Hand and leg swelling in early pregnancy
Warning signs in the twins appear on ultrasound scans and include:
Evidence of a monochorionic or shared placenta
A single placenta
Same sex twins
A thin, hard to see, dividing membrane
A difference in size of your ID twins needs to be monitored 10% is I understand the threshold, we were 10% difference, 3 weeks later, she was dead, so if you go to anywhere near 10% I would ask for weekly scans. Especially if you are 14 weeks up, between 16 and 25 is when TTTS most commonly occurs.
Don't ignore that twin pregnancies are known as 'high risk', a womans intuition is real, if something feels off, wrong go to the hospital, you won't be turned away.
If you really want to arm yourself for the best pregnancy, be aware of what is happening to you, monitor your own weight at the same time daily, keep organised copies of your own scan appointments, and look up what the words mean, if you don't know what the consultant has written ask them.
Each scan, ask them, do you see anything that would suggest early signs of TTTS, that we should monitor more closely for, if you appear knowledgable, they will look more closely.
I wish you all the very best of luck, I wish everyday my other girl was here, but I am grateful to her that she stuck around to 37 weeks so my survivor survived. I don't want anyone to go through what we had to, considerations of termination at a late stage for the survivor if she was severely brain damaged (you have to have an MRI at 28-30 weeks to tell). A pregnancy where one side of my tummy was silent until the other twin grew into her space. Please be informed, information is never a bad thing. I have started to work on a sheet to be given to ID mums about TTTS, (the hospital said they would check it through and adopt it) because it is ludicrous that downs is 1% in pregnancies and you have 4 pages about it from day 1, but when you are in the bracket of an ID pregnancy you aren't given any different information despite it being 15% official figures of all ID twin pregnancies. xxxx
