Am I pregnant ??

Here’s the story:

I’m on Camila birth control which only has the progesterone hormone since I get migraines. My boyfriend visited me 3 weeks ago and we had unprotected sex. He never came inside of me, but there were a few times that made me worry if it somehow got inside. One time it dripped down pretty close and I needed to wipe it off and sometimes (not always) hed finish on my stomach, wipe himself and then go back in for another round. When he left my breasts swelled A lOT, but then a few days later I got a four day period and after my boobs got smaller. I don’t think it was spotting cause it was heavier. I’m still currently on the pill, but recently I’ve been bloated in my abdominal area, gained some weight (not sure if it’s cause I drank a few nights ago and gyms are closed as well) but there’s a lot of pressure down there. I’m also very active I run every day and do strengthening exercises but also have been moody and no appetite. Also have been sneezing a lot with a runny nose but That’s whenever I go outside so it might just be allergies. so last week I bought a package of pregnancy tests, one came out negative the other didn’t work it was blank. This week I took another two and they both didn’t work. I find it odd that 3 didn’t work which makes me more nervous. I have a gyno appointment July 2 but I fear that’s too far away to talk to someone about it. And I am planning on not only doing a blood test but also change my birth control so I am more safe next time. I’m only 18 and my parents are really strict so I feel kind of trapped to be honest and I hope I’m not pregnant. What do you guys think? Am I worrying too much? Do you guys think I’m pregnant?
