Can you get pregnant due to dry humping?

Hello maryan and Susan I hope you can answer my question and give me something soothing words to relieve my fear.
On December 2016, I got engage with some unprotected physical contact with my boyfriend where we both were naked. However there was never a penetration or ejaculation inside my vagina as I'm still a virgin up until now. We were just rubbing and grinding. Although I was far from ovulation that time, I was so scared to death of pregnancy to the point of driving myself crazy about it. I took postinor asap. I've had 7 negative pregnancy test, 4 regular monthly periods and 2 ultrasound done on March and April which all shows empty uterus. I never have any sexual contact ever since then.

However On May 2017 , I thought I was getting over it and can finally accept the fact that I'm not pregnant. So my boyfriend and I had an outercourse where we both were fully clothed all the times. (3 layers including panties, leggings, and his thick shorts) meaning that there was never a penetration inside me. moreover, he did not ejaculate in his pants, on my pants or anywhere near my vagina. He only ejaculated on his stomach when I gave him hand jobs and we washed everything after. We also did not touch my private parts at all. I swear I thought I have gotten rid of my pregnancy scare that happened in December 2016. But when I came back home, suddenly all the anxiety, fear and panic attack came back to me all over again just like what I've been through in December 2016. Do you think I'm at risk of getting pregnant even if we only had outercourse? I don't think I can stay calm until I at least get 5 consecutive regular periods, at least 5 pregnancy test and another 2 ultrasound just to be dead sure that I'm not pregnant. Do you think all that is necessary for this time around? Truth is, I'm so so tired of spending too much over all these tests but I need to give myself some reassurance or else I would drive myself crazy thinking of any possibility of getting pregnant. Maryann and Susan , please help me as I'm only 22 years old and not ready for all this.

So me and my boyfriend are dry humping and i finished him by giving hand job, and some of the sperm went through my shorts not on the vaginal part just the inguinal part and the side of my short but i immediately cleaned my vagina and changed my panties and short, could I get pregnant?

Hi~
i got a few questions to ask
1) dry humping without clothes on with penis rubbing against the ciltorus, likely to have precum but no ejaculation. The guy pee had not masterbate on the day and had pee before humping. Will there be chance of getting pregnant?

2) Just the penis head going into the vagina for 2s. likely to have precum but no ejaculation. The guy had not masterbate on the day and pee before engaging sexual activity. Will there be chance of getting pregnant?

kindly reply thanks!

Hi a week ago my bf and I were dry humping with only our undies on. He came and complete soaked his underwear and that in turn soaked mine as well. It's now been a week and now my breast is starting to be really sore. I'm expected to have my period next week but I'm really worried because this is the first time my breast got this sore. Am I pregnant? Please help me, I'm so stressed :(

Hi,
I dryhumped my boyfriend naked towards the end of March (I think sometime during the week of the 21st), and he did ejaculate on the lips and towards the clitoris on the outside only, but I did wash off right after it happened. Normally I get my period every 23 days but it's been a month since I've had it. Is there any way that I'm pregnant?
Please please help!
