Bean, first of all, I think it's totally normal not to be too devastated. We all know that very early + tests can be tenuous, so I think most of us are pretty guarded especially in the first few weeks. I think I may have had a CP last month and was concerned about my cycles/fertility rather than sad.
As far as the baby aspirin goes, I think it can't hurt. Well, there's a TINY risk of GI problems with it, but it's such a small dose. I know that here, REs prescribe it for anyone with any sort of fertility issue. It's not proven to help unless you have a clotting problem, but they consider it basically harmless and potentially helpful.
Daisy, fingers crossed for you! Which day will be 14 DPO?
AFM, I'm on CD 10 now, when I'm supposed to BD per my midwife. Although I have no fertility signs and no reason to expect I'll O for over a week, I'll follow orders. I haven't been taking my B50 the last few days ... I think I got freaked out it would hurt my cycles. I know most everyone says it'll help, but I'm a worry wart.
