I usually start IVF with 2-3 follicles on each ovary. I took Aspirin for 2 cycles prior to Dec 2013 IVF and started with an amazing 15 follicles. I continued to take it throughout that cycle, only stopping for a few days before egg collection so I wouldn't heamorrage. Unfortunately BFN despite excellent embryo.
Cycles then went haywire and I read Aspirin can cause this so I stopped it but again only had 6 follicles on day 2 of IVF cycle of which only 3 responded, so I cancelled.
Am now taking Aspirin again in prep for IVF next cycle. I have read that it can interfere with implantation and have decided I won't take it after egg collection this time. Perhaps that is reason why embryo didn't implant last time? But I have read conflicting studies and can't decide if I should stop it at day 1 of my IVF cycle or continue until a few days before egg collection????
Did you take Aspirin during your IVF cycle and what was the outcome? Or do you have any knowledge on what would be the best choice?
