Help, could i be pregnant?

Hi, I'm 15 and afab. Will just say this at first because I feel like there could be a confusion with it, but I'm German, having sexual experiences with people in your age range is perfectly legal.

Recenly, my vagina has been kind of sore for no particular reason, which i had been treating with just a regular ointment. Yesterday, I spent time with my boyfriend and I "relieved" him and after that he "relieved me" (we always make sure to wash our hands properly after it's his turn because we don't want any sperm to enter me, obv.)
He fingered me at first, which kind of hurt at first because I was sore and then we just used a round clean plastic object, can't really say what it was, and just did it with that. At some point it hurt really really badly so we just stopped with that. We just got dressed and cuddled for a while after that and about an hour later I went to the toilet and saw that I was bleeding out of my vagina. Didn't really think much of it, have been having my period for almost 4 years now and it was one day early, which is perfectly normal for my cycle.

The thing is, I do not bleed anymore, though I should be on my period. And now I don't know if the bleeding was caused by the soreness or my period, and if it was by my period, why did it suddenly stop? It was not a lot of blood but definitely also not just a small wound as I was still bleeding as of last night, which was about 5 hours after we had our fun.

A quick google search told me that I could be pregnant which scared me. Me and my boyfriend never had unprotected sex, we never even had sex to begin with. The only things we did is "relieving" the other one, but we always make sure to wash up properly before we touch my vagina.

I have also had issues with my stool the last couple of weeks; I've been constantly constipated or have diarrhea (which is kind of normal for me since I have generalised anxiety and IBS), but my stool has sometimes been floating on top or looks kind of "flaky".
Other than that, my cycle as been perfectly fine; my period usually announces itself with heavy PMS, which I definitely experienced over the past week, I've also had normal discharge.

Does anyone know anything about why my period is like this, is the chance of pregnancy high, should I make a test, go to my gynecologist, help?
I'm sorry if this sounds exaggerated, I have terrible anxiety, especially around this topic since my mother is strictly against having any sexual experiences before 18.

Sorry you are in such a stressed and anxious state, but I think anyone would be as well.

Something, not necessarily pregnancy, is going on and you'd be best off getting checked out by your gynecologist or family doctor.

It's easier said that done, but try not to jump to conclusions but, instead, go get the answers from a trusted medical professional.

Keep well

Hugs

I don’t blame you at all for being anxious. It’s always stressful when your body sends messages you don’t understand. I agree with TheGal that getting it looked at by a medical professional like your gynecologist or primary care physician is the safest option. This way you can ensure you are getting the care you need from someone you can trust. I hope you can get some answers soon and find some relief. Take care!
