I think the HCG results in the blood are higher than they are with HPT tests, so I'd think about going, and then get it rechecked next week to see if it's climbing. Did you have bloodwork at all after the m/c?
I'm so sorry that you've had a bad experience nurse. I didn't really like my OBGYN at the women's clinic my doctor referred me to, but I love the nurses. I may stay at the clinic but change to another doctor. I have a follow up this Friday with the OB so I'll see how that goes. I had a chemical pregnancy. I understand what that is, it doesn't stick and basically passes through without ever implanting. The doctor was not sympathetic at all, gave no reassurances, and kept saying "well you were never really pregnant" to an emotional woman 4 days after a m/c. I swear if she had said that ONE more time I was never pregnant I was going to punch her in the mouth. I had a BFP on a home test AND a confirmation positive at the doctors office, plus symptoms and joy. I don't care what the technicalities were, I was freaking pregnant. Grrrr. Thank god the nurse that came in after to do my bloodwork was wonderful and full of great information, and she was also really awesome when I called in during my next AF because I was in so much pain. The doctor could learn a thing or two from her nurse!
I hope you get in to get tested soon and find out soon and that it's a BFP, and they are nicer when you go in. They should not work with women who are pregnant and trying to get pregnant if they can't be more understanding. Shaking my head!
