Me and my girlfriend got intimate and in the heat of the moment I started fingering her. But I forgot that I touched my dick few minutes before fingering her and I didn't wash my hands before fingering her. I do not remember that if there was precum on my dick or not. This was just before 4 days of her period. Than she also had her periods but this month her periods are delayed. I just touched my dick for a second with my fingers. And I used same finger for fingering her. Are there any chances of pregnancy. I also sucked her breast can this increase prolactin and can cause delay in periods.
