Plan B.. should I have not taken it?

Today my husband and I had sex and the condom broke and it was not expired and it was put on correctly. I recently just got off my birth control pills 2 weeks ago because we do want to try for a baby but in several months from now. I wanted to be free from any added hormones in my body. I checked on my period tracker app and I’m in my fertile window because my ovulation day is tomorrow.

I took a Plan B about an hour and a half after having sex but I’m still worried because the app I use of course is only a prediction.

I know it’s a waiting game but I’m just worried and scared.. and I kind of feel guilty for taking the plan B.

Has anyone went through the same situation as me? If so, what was the outcome?

Plan B 3/15

Ovulation Day tomorrow 3/16

Expected period 3/31
