Am I pregnant? So confused

So my last period was November 19th, but my cycles are very irregular, last cycle was 51 days, the one before was 34, and now I’m on Cycle day 60. I have been nauseous, and my boobs have been killing me, my back is so sore, and I’m so bloated that I look 6 months pregnant 🤦🏼‍♀️ I feel like I did when I was pregnant with my other child, but the only tests I took had a line when up to the light but were getting darker, and the digital said no, if I had a 51 day cycle like last cycle then AF should’ve come on the 9th, making me only 8 days late, and I took the digital at 3 days late, and the other tests on the 7th, 9th, and 10th. On the 6th I had what I think was implantation spotting because it was just a tiny drop of very light pink when I wiped, but only once. My appetite has increased significantly, and I’m so tired. I don’t wanna take another test and be disappointed though 🤦🏼‍♀️ I’ll add the tests I took to show you guys, but again they were held up to the light, but you can see that they got a little darker each time.

Brightness needs to be up to see how much darker they get

So is it possible that I’m pregnant?
