Am I freaking out for nothing?

Ok I’m going through a really bad pregnancy scare right now. It all started about last month in early February. I had sex with my boyfriend about two times that month but we used a condom both times and both times he didn’t bust in me. We both know the importance of safe sex and he makes sure to follow the instructions of pinching the tip of the condom and everything. But when it came to the start of my period... it didn’t come and I immediately started freaking out. And me being stupid I started looking into pregnancy symptoms on google and it fucked me up because I read all about implantation bleeding and when I finally started getting blood it was a very light flow at first and I was like “fuck please no” because i can not get pregnant right now and stressed me out even more.But then throughout the day it moved into a more moderate flow where I needed a pad and it continued to the next day but on the third day it kinda stopped then came back about two days after. I was still stressed because my period never does that so I took another 4 tests afterwards and all came back negative. So I was like ok but I still had that fear in me so...skip to this month and I got  my period on time like eve said three days ago. The first two days  it’s was relatively heavy, I was having cramps the first day like usual  but then I got moderate to light yesterday and now today it has stopped and I’m kind of freaking out again because like I said this is irregular for me my period usually lasts up to 6 days. We have not had sex since the first irregular period. And I’ve given up looking shit up because like I said google has me fucked up and it just leds me to stressing more. My dad basically hates the fact that I’m with my boyfriend and is super strict and sometimes controlling, so going to get a blood test is out of the question right now. I’m sorry this was so long but please I just need some advice
