Please help

so my man and I got abit frisky on the second last day of 2017, I had my period so I just have him head while he done what he could to me, I remembered I didn’t shave either so on the way home after I dropped him off I felt around my ass hole but it was hairless I had a tampon in at the time, i have anxiety beyond belief, I freaked myself out and thought I could have possibly had some of his cum on my hand, I took the morning after pill three days after because I couldn’t be at ease, three days after the pill I got my period again, ever since I have been feeling so bloated, gassy, tired and hungry, is this normal? Should I be worried? I have been working a lot more lately as well as taking on much stress.. I’m a stress head and I just want someone else’s opinion if this is semi normal x thankyou in advance

Update - I have taken a pregnancy test and it came back negative but I am also late on my period, please any advice would help,
