Confused... .. . .. ... . .

Hi I need to say this... Yes I'm kind of worried even though I use the bc pill but I need to know what is really happening in my body. ( my partner and I had unprotected sex on the 30th of May. My partner always withdraw but I don't think he did this time it felt like vibrating. Everything was okay until two days ago. I've been sleeping a lot, my breast are very sore and tender, I have abb lower pain like if it was cramps, I have an ugly taste in my mouth, I sometimes feel that something moves really soft but idk what it is. They say it could be gas and when I clean up myself on the paper was a creamy, stretchy, white/little bit of yellow)! What is going on with my body... I'm not scared but I'm concerned and would like to have answers to see what's going on with me.
