I started Gianvi recently. (Just finished my first pack) My period is now late, which usually isn't concerning, but I had sex with my boyfriend within the last week. I did take a pregnancy test, which was negative, but I'm still concerned. Is it normal for your first period to be late when just switching to Gianvi? (I was on a lower dose of BC before.)

He is also freaking out so a little help would be very appreciated
