Help please :)

I need some help as I’m still learning how ovulation works 100%. My husband and I have sex pretty much every night but he has a hard time cumming sometimes. He did cum in me 3 days before my positive LH (4 days before ovulation) and then the day after ovulation. What I’m wondering is, can we conceive the day after ovulation? I know it’s possible but is it likely? My cervix was high soft and open for about 6 days, including the day after ovulation. TIA!!!
