PND symptoms - freaking that I may be pregnant again...or am i just plain knackered?

[fungusmungus]

hello folks
I've posted on the conception page before because I was freaking that I may be pregnant again, but am clearly not (according to numerous pregnancy tests!) - but the more I analyse this, the more I feel my symptoms are just down to good, old fashioned PND and I'm too stubborn to realise this ( and cant cope with the thought of being pregnant again!)
My DD is 9 months old and I've been winding down the BF'ing since mid August. AF still has not returned, and since we were on hol in July - and let our hair down a bit, and the libido was up, I was convinced in August that I must be pregnant... feeling very queasy and had mild cramps in addition to being absolutely knackered... and still looking after DD singlehandedly - DP does a bath in the evening and is trying to understand that I'm at a low ebb.
I have been feeling really low, very achey especially in my arms and knees, cramps in the uterine area and very irritable but have put this down to being plain tired since DD has only just started to sleep through the night and I'm still BF her 1st and last thing.
I saw my GP who did a PG test and blood tests (blood count thyroid etc - all normal) and basically intimated that I shouldnt waste NHS resources and asked if I was depressed, and since then I have done about 6 tests... all BFN, convincing myself that the tiredness, achiness, cramping, dizziness & nausea is hormonal and related to being PG again...
what do you think - has this happened to any of you?
I figure that i could be classed as PND - feel quite lonely, have very up days and mostly tired days when its a struggle to summon up the energy, let alone make any major decisions, have to return to work next week which I'm not looking forward to but recognise that having something else to focus on may be a good thing. Should I talk to my HV? should I insist on something from my GP
as you've probably guessed from this long rant - I'm feeling completely at a loss and cant decide what to do?!! any advice or stories most welcome.
I guess in an ideal world - I wouldnt be depressed, just low and about to get the worst AF of my life?!!!!

just read your message and think you should ask to see another gp and explain your aching etc syptoms again. Also, if you're still BF, you might be sitting in a position, or leaning over at the neck, which is making you really tense. I had the same achiness whilst breast feeding my son. I was bending my neck over to look at him and it made me achy all over as I'd been sat in the same position for ages. Also tiredness can cause loads of strange symptoms but I'd definitely get checked out again. Maybe you have got pnd but if you can find out what the physical symptoms are, you might feel a lot better in yourself. Book a head, neck and shoulder massage too!

thanks Luciemule - think I will definitely book the massage...!
and I'm seeing my HV on tuesday so will mention all this to her.. it's weird, now that I've finally given myself permission to think I'm not superwoman, I feel a bit better. Still absolutely knackered but it will get better I'm sure!

i would see another gp as urs doesnt sound very sympathetic.my first AF after having dd2 was awful.id felt like killing somebody for about 2 weeks b4 and then i was 'on' for 10 days.
