I was at the OBGYN today for a transvaginal ultrasound and the OBGYN couldnt find a gestational sac. She said either its a too early (as in I miscalculated how far along I am), a miscarriage or potentially an ectopic pregnancy. Im fairly certain of my date of ovulation (as I rigorously used those digital ovulation sticks) They took my blood to determine HCG levels and will call me next week if something seems off. She also asked me to come a week later for another ultrasound. I was wondering if anybody has any insight or personal anecdote to a similar situation? I know miscarriages are common and I am mentally preparing myself. Hopefully it's not ectopic. I appreciate this community so much!
