10 Day Late Period!!! 😰

So my last period was January 7th, and I started taking Birth Control Taytulla on January 12th.

4 days later, I called my doctor and she switched my pill because I was vomiting. So I stopped taking Taytull and she said to start the new pill when my next period comes, that following Sunday.

According to eve, my period is 10 days late. Is it because it threw off my cycle?

I am sexually active but we ALWAYS use condoms, and he ALWAYS pulls out before cumming. I also took a pregnancy test and i am NOT pregnant.

When will my period come? Im super confused! Any help would be great!
