Metronadizole gel!!

I ovulated about 1 or two days ago, but now have to use metronadizole gel😩...has anyone used this while trying to conceive or after ovulation?im scared it might interfere with implantation or fertilization of the egg or something !!! After taking clomid I can't believe that this darn gel would be able to mess it all up 😔 I woke up nauseas this morning so idk if that's a good sign of a baby coming ! Please help anyone that has used metro gel while ttc..what did the doc tell you?? Thank you!
