my bf and i had unprotected sex 16 days into my cycle (my usual cycle is 31 days) my last period was april 1st. i havent really been thinking about it as last week i started eating loads and sleeping loads which i thought was just a sign my period was coming. My period is now a couple of days late and i feel totally fine,no camping bloating or anything,im just still eating and sleeping loads but other than that im fine. my period is always on time and they are usally very painful so im just wondering what is going on? Has this happened to any1 else?
