Need some advice..

So I went to my ob/gyn last week bc I hadn’t had a period for 3 months. She suspects PCOS and ordered me bloodwork and an ultrasound. She said if that is what it is she will prescribe me clomid to help me ovulate bc me and my husband have been trying for 8 months unsuccessfully. I did my bloodwork that day but have to go back for my ultrasound next week and I think I started my period today. It’s not very heavy just kind of like spotting right now. But now I’m worried that since my period came that I won’t be able to start clomid right way. Anybody have any experience with this? I really don’t wanna have to wait until my next cycle bc who knows when that will be!
