Opinions please

16 years old and freaking out thinking I could be pregnant. I’ve seen a lot on here recently about a situation similar to me. My boyfriend got a little excited when we were about to have sex and went in raw for a few seconds, but I told him to put on a condom Bc I’ve had too many scares already with him going in raw. So we used a condom after those like 30 seconds and then he pulled out before he was about to finish and came in the condom. So I know hat he didn’t cum in me and the condom was not broken but is there a possibility that I could get pregnant from him going in raw real quick like that? He told me how he did not jack off that same day we had sex so there shouldn’t be any leftover sperm in his penis. The only way sperm could have got into his Pre-cum is if any leaked in from the other gland. Opinions please I’m going crazy. And I’ve had this watery ish / creamy ish heavy discharge for about 2 weeks now and I thought I.T meant my period was coming but still no period. PLEASE HELP!
