Hello, can this cause pregnancy? I was standing in the bus when a man rubbed to my as* for 3-4 times, I'm virgin and at that time I had periods so I was wearing pad.(both were clothed certainly) I'm scared, if semen can get through clothes in pad and then from pad in vagina and cause pregnancy? Please answer as soon as possible, I'm really scared. Thanks in advance.

The odds of you getting pregnant from this are infinitesimal. Unfortunately I can't say they are impossible, but I wouldn't be concerned.

He rubbed your back side, he would have had to rub right on another area, not your rear,

If he was right at the right spot ( don't see that happening standing up on a bus)

So why did you stand there long enough for him to rub 3 or 4 times,
