Bloating? Pregnant?

So I start Birth control two weeks ago and I’ve been getting really bloated. My bf and I did shit in July, it’s been 10 weeks since we did it, I’ve had my period but it was much lighter than usual. I’ve done around 7 tests from the beginning of August to the beginning of September, they were all negative, including the one were I went to the clinic and took a pee test in the actual doctors cup instead of the at home one. Tonight, I took another on at the 10 week line and it was negative as well. Also, the test shown was from tonight, is there a small line?
