Could I be pregnant? (Need some support)

Hey all!

I’m 6 months postpartum with my daughter (I got pregnant on ParaGard IUD) and my fiancé and I have not had a lot of sex since… Every time that we do though... we are sure to use condoms because I don’t want to get back on hormonal birth control that will further mess up my hormones. We are very cautious and have never had an issue where it broke, fell off,, etc.

My period is still not regular- we had sex last week and he tried a new condom we had been wanting to try (ecstasy by Trojan). We noticed it was a little looser fitting than the previous ones but it did not fall off and it wasn’t SUPER loose but slightly looser fit. I was on top and I’m SOOO paranoid something may have snuck out of the bottom of the condom. I didn’t see or feel any semen at the bottom of the condom or on me, i only noticed a clear lube smelling liquid in both places (clearly lube).

What are the chances of me getting pregnant and should I not really be worrying so much? I’m mortified lol. Thanks in advance!
