Hello all,
Here's my scenario,

Me and my boyfriend did [dry sex] , he was wearing cotton underwear and I was wearing cotton pants without an underwear.
He ejaculated while he's wearing his underwear and I may felt some wet area.
1-2 minutes After that, I washed the wet areas [ I don't know if it was close or not to the vagina]
After about 15 hours,  I had my period which lasted 5 days ( as normal )
It's been 16 days from this accident.
Last week, I got my ovulation but it was exaggerated in usual symptoms as I felt nausea and a very bad feeling to vomit + constipation + a very mild GERD.

I still have about 10 days to my next period which is regular (25-26 days).
But am sooo worried and I feel like getting a heart attack.
My questions are,
1. Should I be worried ?
2. Is there any possible to get pregnant from that scenario ?
3. Am I having stress symptoms or what ?

I really can't wait to hear from you guys.

Thank you.

I would safe you are probably not pregnant as its not very likely and then having your period afterwards.

There is no way you are pregnant
