I and my girlfriend had a botched protected sex on the 16th day of her cycle. She normally has a 26 - 28 day cycles and we've been charting for nearly a year now using Flo app. The app predicted that she had her ovulation spike on the 13th day of her cycle. Unfortunately late into the act we discovered that the condom slipped and some sperm may have gotten into her.
We got postinor 2 and she took it within 2 hours of the incident. After another 1 hour she experienced light bleeding, the blood was brown for a bit and later was deep red. It also felt spongy like there was some tissue particles. The bleeding lasted for just a few minutes and that was it. She also experienced cramping in the lower left abdomen for about 30 minutes after that.
She's due today for her next period but she hasn't reported any signs or pms symptoms. She says she feels perfect. We are both worried sick.
Could she have been ovulating on the 16th day of her cycle?
Is it possible that she's pregnant?
How soon should we expect her next period?
