Vaccine interfere with birth control?

Hello everyone

Do you think the covid vaccine can interfere with birth control? Did you get pregnant after receiving it?

I got the first Pfizer one a month ago and got my follow up depo shot on the 30th September. I have been so nauseous the last two days I couldn't even keep water or coffee down this morning.

I have been getting my depo on schedule and didn't use any other medications. I'm just curious as I don't want to waste a test seeing as I am on birth control.
