Clomid first round

I need help. So I'm on cycle day 20 and yesterday I got a line on my ovulation test, but it wasn't as dark as the control. Then throughout the day the surge went away. Then this morning I had another line but still not as dark as the control. Before clomid I ovulated the latest at cd 19 the latest. So my question is. Is any line ovulation with clomid? Or do I need to do something further. Like calling my doc? Please help been tcc for 2 years and this is my first round of clomid
