Help Please!!!!!

Hi everyone. Last month, I had my period on the 7th, and it ended the 12th. I started taking Taytulla Birth Control that Sunday. I started vomiting so I called the doctor 4 days later. She switched my pill and I need to take the new one when my period comes and take tot the following Sunday.

My period, according to eve is 10 days late. I am sexually active, but my boyfriend and I ALWAYS use condoms. I also took a pregnancy test, just to check and I am not pregnant.

When will my period come? I know starting and stopping the BC will throw off my cycle but for how long? Because I only took BC for 4 days then stopped it.

Any help would be GREATLY appreciated! ❤️
