Hello. I Am 22 Years Old And A Newlywed. I

hello. I am 22 years old and a newlywed. I have a 5 year old daughter but we are now trying to get pregnant. In the past couple months I have experienced a lot of ovarian pain specially during ovulation. My OBGYN prescribed me Tramadol 50mg and I was instructed to take 1 every night before bedtime as needed. My question is if I am trying to get pregnant is it ok for me to take tramadol? I only take it when I am in pain due to ovulation but I want to know if it will harm the fetus?

thank you!
