Darn the luck, man! First time sex and you had a condom break!! It doesn't happen all that frequently but unfortunately, once it does, you've been compromised in terms of safety. Glad he hadn't ejaculated yet so we are just talking pre ejaculate which is less likely to get you pregnant. I think it is a chance but very small and would not really worry much. You can take a test if your period doesn't show but it should show. Let us know!
Ovulation trackers are a best guess at most. They aren't measuring hormones to really 'know'. No, this is not how the pill works. You can't take it after you have had unprotected sex 3 days prior to when you might ovulate. It has to be on board when you have the unprotected sex. But again, this sounds like a very slim chance of conceiving. Really.
plus since i took plan b shouldn’t my ovulation for my second cycle be late so my period be late
I say this with empathy but you really need to calm down. You took plan B. Your period will now be irregular for 2 to 3 months. We can not possibly know if you actually conceived in the slim chance you had to do so. All you can do is take a pregnancy test at 2.5 weeks after the condom break. And if it were me, as this is clearly causing you great anxiety, I would cease having sex! It's too much emotionally for you.
Expect a negative test but 2.5 weeks from when the sex happened, take a home pregnancy test. good luck
So, any time your anxiety is reeling out of control again, please read my advice that it is likely Plan B and you can test 2.5 weeks after the condom broke. There is nothing more to add until then. Really.
