Plan B

My boyfriend came home on leave from deployment and we did it a few times the day he got home, the following day I took a plan b but I was supposed to start ovulating the next day… would it still work or no? Ik that plan b doesn’t work while you are ovulating but it’s been a week since I’ve taken it and I have early on symptoms of being pregnant that or normal and most women can have these symptoms but at the same time I have light bleeding off and on and that gets heavy once in awhile and that’s been going on for 2-3 days… it’s too early to take a test and I’m kinda freaking out
