I had my periods on 4th July. My cycle is irregular. Varies from 28 days to 40 days. I met my boyfriend on 13th July. We were casually making out. Me made me touch his penis after 2 mins he rubbed his penis on my hips for about 5-6 seconds. He didn't touched my vaginal area but my hips were in contact with his penis for a short time. During that time he didn't ejaculated. So there was no penetration. I know that pregnancy is not possible unless penis and vagina are in contact but still I am afraid. I am sure that there was no contact between vagina and penis. He only touched my hips. Is there a chance?
