I am approximately 2-3 weeks late for my period. I am usually very regular; Ive been late for a week or two before but I can generally count on my period coming at a certain time. The difference between then and now is that I have been sexually active, therefore increasing my chances of becoming pregnant. My partner ALWAYS uses a condom with spermicide and pulls out well before he finishes. So I became concerned after missing my period and started doing some research into whether I could be pregnant.??
Hi, I understand your concern.  Yes delayed menstruation in sexually active woman is first sign of pregnancy... pregnancy confirmed after pregnancy test is +ve.  But in your case where you claim use of condom with spermicide... it seems to be less likely. Still to rule out any mistake in use of contraceptive. You should go for HPT to rule out pregnancy.  Certain conditions like POD/ Ovarian, thyroid, anterior pituitary problems causing hormonal imbalance/ severe weakness, illness can result in delayed period without pregnancy.  Thanks.
