Pregnant?

I’m on birth control haven’t missed a pill at all I’m on the mini pill I’ve been late taking it sometimes but no longer than 30 mins. This the first month I’ve been late on my period. 4 days late. I’ve been having nausea bad headaches vomiting so it’s hard to rule out if it’s pregnancy or just side effects of my pills so I decided to take a home test. Idk if I’m seeing things but is it me or is the second line very very faint? I’m stressing right now I’m a mother of one and so not ready for another baby lol
