Pregnancy without cumming

Had sex during my ovulation and my husband didn’t cum into me. We had about a 30 minute session after which we stopped as I was not well. After 10 mins he masturbated and he came.

So we had sex without him cumming into me or near me.

Is it possible to get pregnant?

I believe precum happens just before ejaculation and he was not close to ejavulating when we had sex.

It’s my 3 rd day of missed period.

Pls help me understand if it’s possible or not to get pregnant. And is it too early for a home pregnancy test?

Ps I never had delayed periods.
