AF is a bitch

So I started progestrone cream this cycle and 3/28 I was suppose to start AF. AF never fails so show so I figured it was because of starting the progesterone cream. it is currently 3/29 12:50am and AF decided to make her appearance in the middle of doing the deed. lol. of course he stopped because it freaked him out. lol. AF always ruins everything. anyone else start AF in the middle of doing the deed?
