I have irregular periods. My last menstrual period was in April 22, 2014. May 20, 2014, my boyfriend and I had oral sex and were pretty much dry humping, but he had his brief and jeans on, and i had my underwear. He ejaculated twice on my breast and on his pants. No sexual penetration at all, but he gave me oral. It's past the 22nd, I know sometimes my period isn't always exact of course, but I've been pretty paranoid. What makes me feel so paranoid is that since the 25th, I have been feeling these signs and symptoms:
-breast swelling and tenderness
-presence of Acne
-feeling tired and sleeping too much
-low back pain
-bloated and gaseous
Also, I noticed that my discharge has been kind of thick, whitish-yellowish, odorless, sticky discharge on my panties. I know that these symptoms can be signs of Pregnancy and may also indicate PMS. Could I be pregnant? Or these signs and symptoms may be just signs that my period would come soon. I'm worried about being pregnant or something. I need your expert advice.
