I was due on my period on the 28th of August but missed it (I saw a nurse and she put it down to stress or rapid weight loss as there was no chance what so ever of me being pregnant as I hadn't had sex since before my last period, on Saturday the 7th I had unprotected sex, used withdrawal method (yes, irresponsible I know) I took the levonelle morning after pill as soon as I could get it which happened to be around 65 hours after sexual intercourse, the next day I had extreme nausea and headache etc and now have developed a lump in my breast, is the lump likely to be linked with taking the morning after pill and what are the chances that I could be pregnant as it is too soon to take a test and I am yet to come on my period
