question: Im have a regular 28 to 30 days cycles of menstruation. I always have my contraceptive pill. Now i stop it because i don t have supply anymore . Im 51 yrs now. I have my 1st day menstrual period last march 1. I had sex with my husband march 20. Im so worried about getting pregnant. I don t have my menstruation yet. I tried using pregnancy twice and all negative. I suppose to have my period before the end of the month. It is possible for that im pregnant?
