Hi I am sorry about this post but I'm really scared and lost. I had my period on Jan 29th and it ended on Feb 2nd. I ovulated 8th-14th and did an AI on the 9th. Yesterday I exspericined light bleeding not enough for protection just whe I wiped. I then put a pad on and went to bed. Woke up this morning and there was a spot about two quarter sized of dark red blood. Idk if it was because I hardly move at night or what but idk. Then today I have received some bright pink/red blood only wiped and a little on the pad. I had cramps some yesterday and stopped today. Any ideas what this is because my periods not due for a few days or more
