Dry-humped fully clothed found wet spot on my pants at upper part of my thigh my period is 5 days late and pms are absent could that make me preg?

Not likely: Hi hon, It is extremely unlikely (not impossible) that sperm can crawl up your thigh and into your vagina. On a dry surface, such as clothing or bedding, sperm are dead by the time the semen has dried. I am certain your safe but there's no harm in taking an over the counter test to verify. Just make sure your in the right time frame for it to be a valid report.
