When to test again?

Hello! I’ve been on the pill since I was 14 and I’m now 21. My gynecologists office suddenly closed permanently and I didn’t realize until I went to refill my prescription. I figured I’d wait until my new doctor’s appointment in May to see if they have an in house gyno.

I got my last pack of pills at the end of February and got my period (withdrawal bleeding technically) during one week in March.

My bf and I have been somewhat careful. I know the pullout method doesn’t always work but that’s what we’ve been doing.

I did the math and I should’ve gotten my period this past Thursday. I was feeling paranoid the Monday prior and took an early response pregnancy test and got a negative result.

It’s now about 3ish days late. How much longer should I wait to take another?

Thanks :)
