didnt ovulate with first round of clomid?

Bobbi

I am on day 19 of my cycle. I used 50mg of clomid, doing the OPKs, but never got any that looked definitely positive, and I've been checking my cervical mucus and none was the egg white kind. is it possible that I didn't ovulate with this dose of clomid? has this happened to anyone else? did a higher dose make you ovulate the next round?
