Missed period, negative pregnancy test

I’m so confused. I haven’t had my period since March and it’s now May. I had protected sex and two week later I took a pregnancy test and I got a negative result and I still wasn’t getting my period so a couple days later I took another pregnancy test and it still came back negative. I’m so confused because I feel like I gave myself enough time to develop HCG but the pregnancy test says otherwise. Am I pregnant or what’s going on? I’ve been not sleeping so well and I’ve lost a lot of weight from being home due to covid but I haven’t missed a period in so long and I’m so confused what’s going on in my body.
