Hi! Okay so i'm in college and I started having sex with my boyfriend about a month ago and we didn't use a condom once but nothing went inside me. I haven't gotten my period yet and it's been 6 days since I was suppose to get it. My dermatologist prescribed a pill for my acne that is very strong on the hormones and sometimes messes with my period severity. Sometimes it'll be light, sometimes more heavy. i've only been on this pill for about 2 weeks but I had been prescribed the same thing about 5 months ago for 2 months. I don't know if this pill and my new sexual activity has anything to do with my delayed period or if it could just be that I'm pregnant. I have had headaches and I've felt tired randomly. But the pill is said to have that affect on you as well. I had a sharp pain for about 3 seconds once and I didn't know if that was the implantation of something. I'm really worried and my boyfriend and I have been researching and ressearching and I'm planning on taking a pregnancy test tomorrow for it'll officially be one week late. Please guide me in some direction. :/
