Hi there!
So.
I decided to have protected sex, then unprotected sex with a boy, two weeks ago.
I have two problems that add up to one problem.
First problem:
I'm on Cryselle 28-day birth control pills, and they have always worked for the two years I've had them. I have never ever missed a day or was late.
My period started a week and a half early, but was super light. It somehow stopped literally the day I went to go have sex, then sure enough, when we were having sex, it started up again. Still super light, but still there.
That period lasted all the way until I started my blank pills... then it started up super heavy, then diminished down like a normal period should, but I am about two pills off the blank ones and onto my normal pills, and I'm still having a very light period. Very annoying.
Second problem!
I noticed a week after we had sex that I had a rash, right around the entrance of the vagina. It was very painful and tender for about three days, then the last four days it turned into a terrible itch, which is now going down and I believe it's finally gone.
I just figured it was my latex allergy acting up, because I later realized that the man did not use a non latex condom the first time.
But! Aside from the rash that is now gone, I noticed yesterday that my clitoris has swollen up. It's not painful, but it definitely doesn't feel good. It's super tender and uncomfortable. Also, I tried stimulating myself... but I am completely unable to produce self-lubricant...
Now today, I woke up, and my breasts are EXTREMELY tender and a little swollen. I have no idea what's going on!
One last thing, I'm a professional dancer, dancing in studios for about 3-4 hours a day, 6 days a week. I noticed yesterday when I tried to dance, I got extremely sweaty and super tired and nauseous with hardly ANY exercise. This really concerns me. I'll also go to bed a little nauseous, and wake up with a headache.
What's going on with me?
Thank you to ANY suggestions and/or thoughts!!

Also! I am 18 years old, going on 19 in two months.

Pregnancy is going to be a possibility to consider even when using birth control. The soreness/itch could be due to the latex, could be from a yeast infection, general irritation, etc.

See what happens when you would expect your next period. If still off, or doesn't show, try a pregnancy test. If soreness continues, see your doctor for a pelvic exam. Since you are sexually active, it would be wise to have an exam from a gynecologist.

Thank you. I took a couple pregnancy tests, both turned out negative. I'm worried it's a yeast infection..
