Sex after ovulation

Hey ladies! I had EWCM on February 6th and got a positive OPK February 7th in the morning with a little blood when wiped (tiniest amount, it went away after that). I’ve been having crazy headaches and Nauseous. My husband and I have been having sex every other day once my last period ended and then every day from 2nd-7th of February. I woke up this morning, February 9th to pink watery discharge when I wiped (again tiny amount). Anyway, my question is..is it ok/safe to continue having sex. Does it affect implantation?? I’m pretty sure I ovulated..but I don’t wanna risk anything this month by “assuming” and stop having sex. Our plan was to continue every other day until I see a positive test. Has anyone else done this with good results?!!
