Just wanted to give an update...
I got lines on some tests and not on others most of the weekend. My doctor still won't see me until Thursday, which is 3 days from now, but the plan is to do a beta and make sure I'm down to zero, then give me some progesterone to kick start another cycle. She thinks chemical and always recommends waiting for AF to start on it's own. She said even though your HCG may be down to 0, your body can sometimes need time to realize it can shed the lining.
Either way, I'm out and waiting for AF to show. That being said.........I hate FRER. The indents and evaps and super light lines I couldn't tell were either grey or pink or what ever else caused me to lose all hope and confidence in them. I spent so much money on them and I refuse to use them in early testing again.
