Plan B, ovulation?
An_254351 posted:
Hello community.

Long story short I'm finding myself in the anxiety boat of waiting to see if Plan B worked. Me and my partner had sex approx. 2 days before the week of my ovulation was to start. We used a condom but it slipped off after he ejaculated. I am not on any other form of birth control. So immediately I drove myself to get Plan B. Plan B was taken within two hours of this mishap.

Two questions -

1. I keep hearing rumors that Plan B is useless if you are ovulating, however this was two days before I was supposed to even start.

2. When is the earliest I can take a pregnancy test? My actual period is due to start Nov. 28th. The mishap happened on Nov. 9 and was also when Plan B was taken.

Sidenote, the "man" I thought I knew after dating as turned coat and decided to ignore me so here I am alone battling nerves and anxiety. Any help would be appreciated as I am now left to pick up the pieces. Thank you.

Plan B is used to supress ovulation so if you were already ovulating, it isn't going to help. Also, how do you know you were going to ovulate in two days?

The earliest you can take a test is two weeks after the incident.

Remember too that Plan B is basically a megadose of hormones and as such, can mess up your period to where it will be late or you may even skip it all together.

Hello there. I usually use an ovulation calculator. It actually says I was to ovulate on the 14th of nov. This incident happened on nov. 9th. Sorry for the confusion. I'm just super stressed.

Taking Plan B 5 days before you are due to ovulate will suppress ovulation. You should be fine.
