Ok so here's the thing. On January 3rd I had dry sex with clothes on, no actual penetration but I am always fearful there could've been some leaking from the guy and it could've gotten through the clothes. Then around February 5 or so, I got my period. But it's April already and I still have not gotten my period again.

I also started taking the medication Victoza (liraglutide) in mid-March. I do not know if this could be tied to the absent periods.

AND I recently noticed that my vagina looks purplish or kind of dark, I looked it up and it seems that is Chadwick's sign -- a sign of pregnancy! Could I POSSIBLY be pregnant? Or can the purplish color in my vagina be caused by something else, like the Victoza? Please help, I am really worried.

You'd have a better chance of getting hit by a toilet falling from space, than getting pregnant having dry sex with your clothes on.

If you are pregnant, pick 6 lottery numbers between 1 and 49, because odds are you'll win millions.

Really, this is not possible. The only way you could be pregnant is if there's something you're not telling us. Have you had sex? If so, that can cause pregnancy. The episode you described, not a chance.

Good luck.
