I found out when i ovulate is somewhere around the 15th but i don't know which days me and my husband should try to conceive?

Around the 15th: If you are ovulating around the 15th then you have sex in the days around that day to maximize your chances of getting pregnant.

Ovulation charts: are the best way to track your ovulation, as some women do not have a 28- or 29 day cycle, rather 24-day or 32 day. Ovulation charts use your basal body temperature and/or cervical mucus thickness to gauge where you are on the menstrual cycle. It has been proven to be much more predictable. You should starting doing it 3 days before and every day (yikes) until 3 days after to maximize sperm egg
