Can drysex with 3 layers of clothes with precum lead pregnancy? my period is late and i have had sore boobs cramps, dizziness and headaches

Possibly.: It's possible but unlikely if you only had the one encounter you described. However, if you've had closer encounters in the past 4-6 weeks, that increases the chance. It's just as likely that your period is simply overdue and all these symptoms are from PMS. However, better be safe than sorry and take a pregnancy test.

Unlikely: do a preg test and if negative redo it in 1 week
