Condom broke (lots of TMI)

Has anyone here actually gotten pregnant from a condom breaking?

I'm trying not to be paranoid. About 3 1/2 weeks ago when my husband and I were having sex, the condom broke. But, I looked at it after we were done, and there was still a lot of semen in it. So it didn't appear as if much had even leaked out.

And i wasn't ovulating that week. I started my period about 5 days later.

I guess the reason I'm worrying now is because the last two days I've been peeing non stop, and I know that can be an early sign of pregnancy. But (more TMI) I'm also super constipated right now, and I always pee more when I'm constipated. And I've been drinking more water, so I know that's adding to the increased urination.

I haven't really noticed any other symptoms. I already deal with chronic fatigue and headaches. And my boobs aren't sore or swollen at all.

And it's too soon to know if I missed a period.

Am I being paranoid??? Or is there a likelihood that I could get pregnant from the condom breaking???
