Ok well im on bc I use the patch and since I got on it my periods have way lighter and not nearly as long so I dont pay tgat much attention to them and I had unprotected sex like three months ago. Anyway recently ive started putting some things together like my breasts are super sensitive and my nipples especially and thats normal for bc but its gotten worse and for the last month or so ive been getting a lot of pains on my groin area kind of like cramps but not as bad but its like all the time and ive been super dizzy lately and if I get up to fast I have to catch myself on walls and my sense of smell is way better then normal ive been getting nauseous over like crazy and im always tired to the point of my teachers asking if im okay. So I gues im just wondering if I could possibly be pregnant?
