Scared I’m gonna miss my period

So last month I took plan b, the year before I took plan be 3 or 4 times. Not for birth control but bc I actually needed to take it, cuz the condom would break and we didn’t know till he finished.

But this time I took it, I legit told the dude “You cannot cum in me, I’m not on birth control” and of course he didn’t listen. I took it the day after though. I know it really messes with my period too cuz I missed my period by a week and it lasted 5 days instead of 7

Should I message my dr and ask her to do a blood test? Should I wait a few more days? I’m 3 days late as I can see. In the past I’ve had problems with my period in the past we’re I’d be a week late (before I ever knew about plan b) If anything I know I’m probably not pregnant bc at the urologist he was checking my bladder and I know with ultra sounds it shows the uterus too. But he didn’t say anything. I’ve been cramping though and have been very gassy and I’m breaking out bad.

Oh I also have anxiety like really bad
