Morning after pill - Makes no sense

Feb vacation on a Wednesday I had sex drunk but my man was sober. I wake up in the morning and he told me he came in me. I didn't have money to get a day after pill until the 3rd day it would be effective to take it. I got my period right away. But it became heavy and 5 days instead of 7. I kept pooping and my stomach has been bloating but it just doesn't feel right. Everything I eat I poop and I have no appetite anymore. Today my stomach feels normal for the first time in weeks. When I read the side effects it said it would only last a few days but my body has been feeling off for a good month now. I'm scared to find out😓
