Had sex with a guy

Hi guys I had sex with a sexy man after drinking and told him not to come inside of me unless he wants me to get pregnant and he said he doesn't care he wanted children and said he wasn't just saying that just because he wants vagina lol which I can read people pretty fucking good lol. HE CAME IN ME FULL ON but I'm on the ring,( I'm 22 years old btw), this was about 3 days after my period about 1 week and 2 days ago but I also took a shower after cleaned in with soap and water and put that jet shit on high up in my bladder lol. I know but just a reminder we did drink, you know how that situation goes. But now im experiencing bloating, a ton of abdominal pain, cramping and have been losing taste in certain type of food. Don't tell me of for weeks is when you start feeling it bulshit because with my first I knew 2weeks in advance lol. Any of you gals experience this with your children though?
