Hi, I am 19 and I am new here. My bf and I have been together a few years and we have sex with a condom. Every time we have sex, we are scared to death when the period comes, to a point that he doesnt want to have sex. But anyway, this month we had sex a few weeks ago a couple times and everything went well, he used a condom, and he didnt go either. So it seems we are careful, but its been almost 35 days wtihout a period. Ive been having irregular periods between 32-34 days, and I have just starting takign prescription drugs also,,,but anyway I took a preganancy test yesterdayand it was negative but it said to take 1 day after missed period and I dont know if I gave it enough time. Well I am very worried and does anyone have an opinion on the effectivenss of the test or how I could be pregnant. Thanks so much
