Thoughts??

So I had sex about two weeks ago. We used spermicide and condoms. He never came, but there was a bit of pre cum. The condom broke, and it was about two minutes later we noticed. There’s been sex since then, but always with a condom and spermicide, and he doesn’t come. I’m now three days late for my period. I’ve been hiking more lately, but I haven’t really been stressed. I’ve been getting cramps like my period is going to start, but to no avail. I have normal discharge too. I’ve been late before, but for the most part i’m regular.

Do you guys think I should be concerned about pregnancy?
