Hello. September 2017 I had a miscarriage, my last period was the beginning of November so it’s been 4 months without a period. I have taken tests and they have all been negative. Yesterday I went to the doctor and they gave me a test and it was positive... I took some more when I got home and they were positive, went to a pregnancy center last night and they were positive. So my question is, I made an appointment obviously but will they do an ultrasound to figure out how far along I am since I have absolutely no clue? Is it possinle for me to be 4 months along and get negative results til now? I’m in such a shock.
