Too early or you’re stressing?

So I just had my period from the 4-11th of this month. On the 12 and 13th, I had unprotected sex🤦🏽‍♀️ on the 15th, my friend gave me 3 bc pills to take for emergency contraception( saw it was equivalent to taking a plan b). Now I am experiencing bloating, weird lower abdominal pain( kind of equivalent to bv but with weird cramps), and constipation. I suffer from bad anxiety and I just wanna make sure I’m not overreacting to the symptoms of taking this pill. Any help is appreciated.
