Help! Is this normal?

October Momma • 22 year old happily married mother of boy girl twins, Emma and Alden, born 10/11/17😊
I took prometrium this cycle to start a period. I'm on day 12 now. This is my last day and until now I've felt nothing. It's been 30-60 minutes since I've taken it and I feel completely drunk. I can't walk in a straight line or focus. I don't know what to do. Is this normal? Just writing this is a struggle. Thank gosh for Autocorrect! Without it this wouldn't be understandable.
