My fiancé rub his panis on my vagina just 4 days after my periods ended.I had my periods on 24 Oct and it ended on 29 oct and the activity happened on 4 nov. My periods are irregular and hence I don't know my ovulation cycle. His panis didn't enter my vagina as it was my first time and hence it was very painful.So he just rub it for few mintunes on my vagina. I am not sure about the existence of his precum neither I know when he last ejaculated.But he urinated ones before the activity and he did not ejaculated after rubbing his penis on my vagina that day.Now I am scared of getting pregnant.Can you help?

He shouldn't rely on urinating to remove any remaining sperm from the previous ejaculation. While not likely, pregnancy can still occur if some sperm find their way into your vagina and you are within a few days of ovulation.

If you are not ready for even the slightest possibility of an unplanned pregnancy, his penis should not come in contact with your vagina, even just rubbing on it.

Even if he wears a condom, pregnancy could be possible, as no form of birth control is 100% effective.
With irregular periods, you'll just have to see when you have the next one. If you wanted, if no period after 4 weeks, you could try a pregnancy test.

Again, pregnancy may not be likely from what you describe, but it's not impossible.

It is very unlikely, but there does remain a slight possiblitlity.
You are just going to have to wait and see if you get your next period or not.

For next time, always use protection, but even condoms fail and pregnancy can happen

There are a lot of other equally clueless people that become parents every day doing EXACTLY what you were both doing.

Have you ever heard of Sex Education? You need a class.

You need to learn a little bit about how all this works before you play adult games.
