Need Answers, Please No Hate

I’ve recently only had sex a few times with protection and extra protection, as in condoms and spermicide because we want to be very cautious. Once after, there were a mix of fluids and I noticed it was more than usual (sorry for TMI). We couldn’t tell if the condom broke or not but my period is 2 days late and I’ve felt no usual symptoms. I understand that stress may play a factor to my period but some answers would be relieving.

Please no hateful comments, I believe we were extra cautious and made sure to be well prepared and educated but there’s only so much we could learn
