Concerned.

I started my first pack of birth control this month and this is the week my period is supposed to start, my period normally would’ve started in a few days. I’m concerned because now I have very little blood and it only comes out if I wipe and, here comes some tmi, if I push in a little bit. I’ve also just become sexually active and didn’t know if that affects it also. I was just wondering if this is okay (pictures is what it looks like when I wipe) for the first month of birth control. Sorry for probably being over paranoid but I really need help! Thank you for the help in advanced!
