Clomid questions😊

I’ve been given Clomid to hell me and my husband have a baby! We’ve been trying for about 5 months now and my cycles have been somewhat irregular (not horribly just enough to make it hard to know when I ovulate), varying from 21 days to 25 days, with my periods *typically* being around day 23. I took Clomid 50mg on days 6-10 and it was my first time to ever take it. Does it delay your period? Today I’m on day 26 and my period still hasn’t come, which I know isn’t horribly late for most but it’s unusual for me. I took a pregnancy test two days ago, and it was negative so should I wait to test again or is it probably just the Clomid? I don’t have pcos, endometriosis, and all of my hormones are in normal range. I took an ovulation predictor kit this month and it was positive, so I don’t think I don’t ovulate. I’m just very anxious and confused and I know I need to be patient but it’s just so hard!! I just wasn’t sure if having longer cycles was typical for Clomid

Thank you so much!!
