I have just got back from first gp visit and the most important question I meant to ask him I've ended up walking out and not asking 
After 5 years trying the only thing we did differently the few months leading up to me concieving naturally was I started taking low dose aspirin. I asked the ivf nurse after my last go failed if its safe while concieving and she said it doesn't harm you and its worth trying. So in the few months before our nxt attempt I took it
(I've never been tested for thick blood but I do suspect a slight issue)
Anyway, I've finally got my longed for bfp and I don't know if I should carry on taking it, I forgot to ask the doctor..its low does, I've googled and studies say its safe but just want to make sure. Midwife due to call me at some point but not sure when xx
