Late Period and Clomid

So I have been TTC for 1+ years and started my first round of Clomid June 19-23 (cd3-7). I have been having extremely short anovulatory cycles usually lasting between 16-19 days. Never more than 20. They actually used to be shorter but taking progesterone for 10 days helped.

Well anyways! Now I’m on cd24, which is super weird for me. Can Clomid increase your cycles that much? Has anyone experienced this? I’m 4-5 days late. Not sure when I ovulated. BFN so far... could this be a good sign? I was really nauseated for a day a few days ago and my nipples have ached like no other for about 3 days. No cramps, really. Any help is appreciated!
