hi i had a laparoscopy on the 22nd of October and i got my AF on Sunday (the 21st so 30 day cycle, usually a 28 day cycle.)
Was the Laparoscopy due to a MC or possible ectopic? if so then id wait about a 4-6 more weeks for AF but you get worried. I hated waiting i moaned about it everyday but it takes time for the body to get back to normal.
And as for the unprotected sex, that wont affect your AF at all. Unless you ovulated on thursday.
