Good evening. Ovulation is approximately 14 days to your next period. Anyhow you predict it, it maybe a day or 2 or even 3 different depending on if your period eventually delays or happen earlier than predicted.
Whether you ovulate 29th, 30th or 31st, since you staying with your husband till 31st I advise you have sex everyday as those days are all on your fertile days.
Having sex everyday doesn't decrease your chances of getting pregnant. If you wish, you may leave a day in between but don't plan on having sex on only one day as the more regular it is, the greater your chances.
Hope you have started daily dose of folic acid 400mcg, it's important you do.
All the best.
