Just curious...

Me and my husband had sex on Sunday. Later that afternoon I started spotting, I was thinking could I have started my period. BTW I don't start until the end of the month. So anyway later in the evening I checked to see if I was spotting again and I wasn't it was clear discharge sorry TMI. Monday comes and no spotting. Than all day this morning and afternoon no spotting. Until this evening I spotted very lightly with cramps. What can this mean???
