I had sex Sunday 9 pm Sunday night, and again on Monday around 8 pm. I took Plan B on Monday night after the sex. I took another Tuesday afternoon just to be safe because I also had sex Tuesday morning but he pulled out. I have a UTi and took a cephalexin today Wednesday morning. I’m just concerned if it will affect the Plan B that I took the day before ?
Will cephalexin affect Plan B?

Oh my goodness. Plan B is a huge dose of artificial hormone for your body to deal with. It's meant for total emergencies.
It's not as reliable as regular hormonal birth control. It's simply worth a try in an emergency. Relying on Plan B as your birth control could see you ending up pregnant, if you're not already
If you are already ovulating, then Plan B may not be able to help you avoid pregnancy. It's possible it may work in other ways, but not proven. You can see that on the Manufacturer's website, where they're careful to use the words possible, & may.
In the scenario where you're around the time of ovulation, I'd suggest Ella, instead of Plan B.
Cephalexin does not effect Plan B.
