question about ovulation

Mrs❤️
Can anyone tell me what cycle day you started taking OPKs after finishing your round of Clomid? I'm on my 4th try with Clomid and never tested while on it because I've always heard not to take them if your taking Clomid, but I see so many people still taking them. I've also read online to wait 2-3 days after taking the last dose to test for an accurate reading. Any help would be great! Baby dust to everyone!!!
