My boyfriend fingered me on the 25th of May and since I was worried that there was sperm on his hand I took an ecp within 36 hours. I experienced medium to heavy flow after 6 days with cramps for 5 days. Now today I am 4 days late for my period. I took a pregnancy test which was negative. I am also experiencing mood swings, breakouts, food cravings and backache like I always do during PMS but I'm not having any cramps. There has also been mild spotting today. When will my period arrive?
