Was I pregnant? What to do?

Hello girls, I'm still trying to process everything ... Last Monday my period was delayed 2 days, so I took urine and tested positive. I scheduled a doctor's appointment on Saturday because I have high blood pressure, so I have to follow the pregnancy from the beginning (I had to change my medication too). I took another pharmacy exam before that and tested positive again. At the doctor, the urine at the time was positive too, but I did the blood also (which was not ready at the time). I left the doctor and followed my day normally. On Sunday morning I noticed a bleeding. I went to the hospital and the doctor asked me why I thought I was pregnant. I said I was trying, I had sex during my fertile period, my period is very punctual and I had done 3 urine tests. She said that my Beta hcg was only 22, and that this was little, but that over 5 is already considered pregnant. She said that it must have been a bad formation in the middle of the road that made it not work.

My question is: was I even pregnant at some point? This bleeding began to increase and in my opinion it seems a lot with my period itself. I researched so much about false positives and found nothing. From what I understand, the false negative happens, but false positive is practically impossible. Is this blood I have from spontaneous abortion? Will I ovulate in the next two weeks? Should I keep trying this month or should I expect the next one?

I was got confused ... And also sad and feeling a bit stupid for thinking that I was pregnant and maybe had never really been pregnant. 😞
