Possibly pregnant or worrying for nothing?

I’m about to get married so being pregnant would not be be the end of the world but I’m just looking for some other opinions on if I should take or text or just leave if. October 10th-16th my fiancé came home and we had unprotected sex, like a lot. I’m not on any birth control but I took plan b the 13th and the 16th. I normally never take things like that but after looking it up I took it the first time and I called and asked my OBGYN and she said it wouldn’t cause any harm to me if I took it the second time. This caused me to get my period from the 18th-24th when I wasn’t supposed to get it until about a week and a half ago. With that plan b induced period, I should’ve gotten it two days ago, and there’s nothing. And I’m noticing a lot of clear, cervical mucus but I’m thinking ovulation but I’m not sure.
