So I went to the doctor today. She did a urine test in the office and it was a BFN. But I had my BFP in a baggie in my purse to show her (haha she said she'd seen much grosser things). We talked about my symptoms and the length of time since my last period. She asked if I read the test within the time limit, and I told her yes, I had, but it had darkened up significantly after the fact. She said normally a + followed by a - would make her think miscarriage, but she thought I'd have had a period by now in that case. We talked about the possibility of ectopic, but she said by now I should have pain if that was the case and I'm not having any pain.
She ordered blood work at my local hospital, which I'll have to do tomorrow morning because I can't afford to miss work unnecessarily.
So... no answers yet. My doctor said it wouldn't be the first time she's seen a pregnancy that inexplicably didn't show up on the urine tests. She said keep taking folic acid and otherwise... we'll find out soon. I guess.
