Heparin shots

Ana
Hi ladies,
I'm on my second <a href="https://glowing.com/glow-fertility-program">IVF</a> cycle and 2 months from turning 41. We had a pregnancy on cycle 1 but it stopped at week 8. 3 transfer of 2 blasts each and no baby.
After loads of test they found I have some predisposition for thrombofilia and I'm now on heparin shots twice a day. We did a transfer a week ago and the wait is though as usual.
Anyone on heparin also?
