This may be a silly question

Sorry if this sounds stupid to anyone.

I came off my period 3 days ago and Me and my boyfriend had sex yesturday and he ejaculated in me as we trying for a baby but I couldn't even have an orgasm and honestly dont no why.

Anyways today we spiced it up alittle and we used some toys which made me orgasm.

Is there a chance I can still get pregnant by this as I've read sperm can live up to 5 days in a woman? Or is that silly to think?? Or is it to soon after my period.
