Question about medication I was prescribed today


Me and my fiancée are ttc. She’s 29 and I’m 24. We’ve been trying for a while but I think it may be bad timing. She does not have pcos and I took a sperm count and mobility test and mine was normal so we are going to try and have sex around her fertile window for sure. I have high blood pressure and today my doctor prescribed me a calcium channel blocker called norvsac. It’s not on the list of specific side effects but I heard that these medications can prevent sperm from merging with an egg. I have not taken it yet and my fiancée ovulates on Saturday. I’m not sure if the infertility effect is true and if it is, I’m not sure if it effects sperm immediately.
