Conception

CAN YOU CONCEIVE THE SAME DAY YOU HAVE SEX IF YOURE OVULATING?? Say I had sex today

09/05/2020 and I’m ovulating would I conceive ? But implantation technically doesn’t happen until 9-12 days after right ?? Someone please correct me if I’m wrong. So the day I had sex 09/05/2020 would already make me 2 weeks right ?

Ps: my period is irregular so wouldn’t go by last cycle
