Hi, I am 17 and have had protected sex (with a condom that was on the whole time and did not break) one time this month. I am a few days late on my period, which sometimes happens due to stress, but I have been getting a lot of gas and cramps for the past few days. Yesterday two properly performed first response digital pregnancy tests came back negative. However, I still have a strange pinching cramp where my bottom right ovary would be. Is this cause for concern? It it somewhat on and off, but I also have period-like cramps on and off for the last 2-3 days but I haven't gotten my period. I feel very scared because my parents don't know I'm sexually active and I have access to a drivers license but not a car yet. I cannot be pregnant or have a child at this time.
