Possible Pregnancy [kinda urgent help please]

ill try to keep it short, i had unprotected sex April 11th and had the bright idea to let him cum in me since it was the second day of my period but my period stopped that day. I have taken at least 10 pregnancy tests since then, the most recent being on June 9th (two that day actually), and they have all came back negative but I still have not had a period since and by came back negative I do mean NEGATIVE, like the digital ones said so and the line ones didnt have the slightest hint of a second line under any lighting after the time they say to wait, youll just have to take my word for it i guess.

add on, my most recent 3 were the first urination of the day and they were still negative.

Do you guys think im pregnant despite the tests? because I do and the reason I haven't just gone to my primary physician is because I am 18 but still live with my mother and I dont have the doctor's phone number and there is not way I am telling my mother but I think im going to try to schedule my own appointment tomorrow morning by finding the doctor's number myself online since I know his name.

Any feedback at all is appreciated except for telling me how stupid I am because, yes, i already know and would not like to add to my current level of self hatred.

also I know the exact dates because i track my period and sexual activity.

TL;DR

insemination April 11th (second day of period) - period stopped - 10+ negative pregnancy tests as of June 9th - thoughts requested
