Thanks to all who commented yesterday. I have taken prog before and gotten my period while taking it, I just haven't experienced taking it with estrogen.
Today was the day I was supposed to have beta #1. I haven't had anymore spotting, but have had a bit of cramping. I broke down and took an HPT yesterdy and got a very faint pos. No rejoicing here yet, having experienced both a chem preg and a m/c. I will probably end up taking one again tmw. Even if it's pos, I'm holding steady at 'skeptical' until I get my official numbers on Sunday.
I hate this part!
