So on Nov 25 I lost my virginity. The month of Nov I'd say my period ended around the 16ish. It's Dec 19 now and its been 3 weeks or so since thenm I only had sex that one time and of course there was no condom on. He didn't inside me but could the pre have done the job... After he came on me I went to the bathroom washed myself off and well I'm pretty much worried now waiting for my period I don't want to stress about it cause the stress could effect the day it comes but I just need an answer about the precum and if losing it changes your cycle up.

SO you wanted to get pregnant right away?

No condom means you WANT a baby NOW.

It doesn't matter what he did or didn't do. We call people that use that method of birth control parents... because the moment he put himself inside you... you could get pregnant... even if its only one second.

A guys penis is EXACTLY like a leaking garden hose... you don't have to turn it on to get wet.

And incidentally... the loss of virginity hgas NO effect on your period... you very well might have gotten pregnant... wait a few weeks and take a HPT if you don't get your period... its too early to test now...

? Or course there was no condom? Why, of course there should have been one, all careful people use condoms at least. So I agree you made a choice to get pregnant

And yes there are sperm in the early fluids, so yes of course you could be pregnant now.
Even with a condom there is a 3 to 10 percent failure, so even with a condom you can still be pregnant.

The loss of virginity has no effect on the timing of your period.

Stress can and pregnancy can.
