I am 19 years old and in my first relationship. My problem is (and I'm not sure why) is that I'm INCREDIBLY paranoid about getting pregnant, probably due to the fact that it's the worst possible scenario that could happen in my life. I have discussed this fear with my boyfriend. Several weeks ago, I began experiencing breast tenderness, soreness, vertigo, and nausea. My period came three weeks late, and that was about two weeks ago. I am still experiencing nausea at times and am totally paranoid about what seems to be abdominal swelling and this weird line down my stomach. I am usually a pretty rational thinker, but everything seems to go out the window when it comes to this. I should point out that we've never actually had intercourse. The extent of what we've done includes making out (with me lying on top of him), and at one point he sat on my legs and rubbed my back. He has touched my thighs and breasts but we have NEVER taken off clothing. I just need to be reassured that I'm probably stressing over nothing.
