My husband and I have been having sex a couple of days before and after I ovulate what are my chances of getting pregnant. I've been taking prenatal?

80-90% in 1 year. 80-90% of couples having regular intercourse (2 or more times per week) will conceive within one year. If after a year you have not become pregnant, you might consider seeing a fertility specialist. Good luck, and keep taking those prenatal vitamins!
Timing correct. Your timing strategy sounds correct; the chance of conception for a normal couple in a natural cycle is roughly between 5-20%. Around 85/100 normal couples conceive within one year. If you do not conceive within a year, or 6 months if you are over 36 years old, a fertility specialist or knowledgeable ob-gyn can help.
