Am I pregnant?

Naomi

I took my 6 months clomid course but I think I took it wrong so finished the course anyway. 1 month after finishing clomid I had my period all was fine throughout taking clomid too, all periods fairly normal then now I’m 18 days late..took about 5 pregnancy test and all BFN. I haven’t taken one in about 3 days but I’m just looking for opinions or experiences?!

Thank you!
