Can having sex often during ovulation decrease the chance of becoming pregnant?

My husband and I are trying to conceive our second child. I took an ovulation test for the past week and it showed negative every day until this morning so it was positive for my LH surge. If we have intercourse twice a day can it hurt our chance of becoming pregnant? Or does it not matter? Answers please everyone!!!! Ovulating and hoping to conceive this month!!! Thank you!
