I hope I’m not pregnant

Early in October I was talking to this guy and we had sex and yes on birth control I took plan b the next day and then On October 26 I went out with this guy and we had sex yes I was on birth control but I have anxiety about it now working so I took option two. So a week later around November 10th I had a 3 day period it was right on time for my period but it was only 3 days now I’m waiting for my period to come and it’s been a month now and I do have discharge and it’s kinda hard to tell whether I’m ovulating or is it just normal discharge it’s like clear slimy and slippery. Help meeee!!!!!
