UPDATE !!! HELP ME I’M ONLY 16 PLEASE GIVE ME AN ANSWER❌❌❌😫

First of all I’m really scared. I just opened this account and took this app my friend told me about and said that here people are so supportive and helpful about problems girls/women have. I’m so stressed and scared please help me. I’m 16 and last week I was over my boyfriend’s house and did some things ya know, touching, kissing and got fully undressed. He touched my vagina with his penis a little and I don’t remember if there was pre-cum or not I’M GOING CRAZY😭 He then came away from my body and 2 minutes after fingerd me and I think his fingers were a little wet or maybe I was wet I HONESTLY DON’T REMEMBER ANYMORE! I’m literally crying myself out all day about what I’ve done and never doing it again cause I’m still young and definitely don’t want a pregnancy to happen😭💔 my bestfriend&boyfriend; tell me not to worry and being supportive but still I can’t calm myself I’m shaking and having panic attacks😞 PLEASE help me, tell me the chances, I don’t wanna get pregnant😔 my period is due in 10 days according to this app. HELP ME PLEASE!!!!!

P.S : I’m a VIRGIN, never had sex, and never planing on having until marriage.

UPDATE 1 : I feel like I’m having some light cramps, is it possible to be signs of my period coming or maybe something else😩??

UPDATE 2 : I did a pregnancy test with my first morning urine and it came back negative. Can I rely on it or no? Should I test again?

UPDATE 3 : I think I got my period, I’m on cycle day 28 today, I usually have a pretty regular cycle with a 28-30 days and this time I think it was 28 days. For the past few days I’ve been feeling some light cramps and a little sore boobs as usual, and yesterday & today in the morning I’ve noticed some light brown discharge and now when I used the bathroom, I wiped and I noticed blood mixed with discharge it was light red. I’m worrying if this might be implantation? Can it be?
