Eh oh? Help? ❗️

This might sound stupid but...

▪️I had sex Sunday & Monday without condom and he finished inside me. Tuesday I switched birth control pills randomly.

◾️I know that you’re not protected until a week after taking a new pill. I’m on Lolo now.

◾️I went from a high estrogen pill to a low estrogen pill.

❗️Could I fall pregnant since the sperm lives 5 days and took the new pill a day/two days after having sex?

If yes, when should I take a test? Two weeks from now? I don’t have periods and I know it’s possible to test two weeks from sex to get an accurate answer.
