Ovulation question...

Hi everyone!

So my doctor put me on 100mg of Clomid, without having af. He said I could start taking it right away since I don't bleed and my first day would be CD 1. He told me I should be ovulating around the 14th, but should be doing OPKs just to make sure.

I'm currently on CD 11, but my OPKs are negative.

I mean no sign of any second line at all, negative. I'm really starting to worry. Is this normal? Will I see a start of line soon? I haven't ovulated in about 2 years and I'm so scared. Been ttc #1 for over a year now!!
