10 days ago I had sex with my boyfriend. We used protection but it seemed like the condom broke so we continued without one. He didn't came in me. My period should have started 30. Of may and now it's 3. June and today I got some sort of spotting. I had cramps like I usually get with my period but all I got was some kind of brownish-white discharge. I see a lot of people say on other posts that it could be a sign of early pregnancy? Could I be pregnant since he didn't came in me and it wasn't on my fertile days?

In reverse order - you don't know 100% that this was not one of your fertile days; there is semen in his pre-ejaculation fluid.

Yes, you could be pregnant.

The usual recommendation is to test 10 days after your missed period, according to package directions.

Pregnancy is possible even when you use protection. The fact that the condom broke, and you continued without one, raises the chances of pregnancy. There are more than enough sperm in pre-ejaculate to get you pregnant.

Wait until your period is at least 2 weeks late, then test using first morning urine
