Hi girls, hoping to get some opinions and advice.

I have recently been advised to take aspirin for ANA when I next cycle. The Ob that advised me to do this said to commence aspirin following +ve BT. I'm worried that I may never get a +ve result this way and so agreed with DP to start taking it the day after EPU which is the day before TF. My rheumatologist at my appt yesterday told me to not be taking it at the time of TF and to wait 24hrs after TF before starting aspirin.
I just feel so confused atm and am unsure as to what to do. Any opinions, advice, experiences greatly appreciated. TIA.
