I have been taking ortho tri-sprintec for 4 months now and I have never noticed my usual cramping during ovulation. The past couple weeks I haven't been taking my pill at the same time, and I missed taking it in 24 hours span. The other night I definitely had my old cramping pains that I got during ovulation and I checked an online ovulation calendar and it was saying i should ovulate the same day that I felt the pains. Ive had plenty of sex this past week and my husband and I don't use condoms. Should I be worried about being pregnant?
