Experience with Plan B(Update)

I just took a plan B pill. My husband and I had unprotected sex last night and he didn’t pull out 🙄. We are currently TTC and I got a positive opk yesterday afternoon and again this morning so I took the plan B pill as I don’t want to get pregnant this particular month as it’s a lot going on and I’d much rather try for next month. Which is why I got up early on a Saturday morning and rushed off to get it. But now I’m seeing it messes up peoples periods. Can anyone share their experience with it?

Thank you.

UPDATE: First I want to say thank you to everyone who answered my question. I never used plan B before now so it was a gray area to me and I never plan to use it again. It did however work because I took a test and it’s a definite Negative. Went and got a blood test and that’s another Negative so looks like I’m not pregnant and I’m going to get my period when I’m supposed to or maybe a day earlier. 😁
