weird situation any help would be appreciated! last Thursday I took a digital home pregnancy test and got my bfp! Friday morning I went to the doctors to get the results on their books. so they did another pee test. the results came back negative. I have never been treated with someone disrespect in my life. I hope the results at the doctors are wrong. the nurse refused to do a blood test. I've had a ton of pregnancy symptoms and I am a little nervous it's a chemical.
