Had sex on Feb 2nd. Took pill less than 24 hrs on the 3rd. Was not ovulating at the time. week later (approx 5 days) started feeling the symptoms (sore breast mainly but no darkening/enlargement of areoles) now two weeks later I'm experiencing cramping & bleeding (if I stick my finger up there) no spotting. my period is due on the 22nd & I think I was ovulating this week. I don't think it can be implantation bleeding because that happens 10 days after you ovulate & usually I get my period the last week of each month (February is a shortened month) could this just be an effect of the pill making my period come earlier than usual? (Also cramping is not slight. implantation bleeding cramps are slight)
