Ok I need some advice.

This will be my 6th round of clomid. Af showed on friday at least I think. I had spotting most of the day and around 6 it became a steady flow. But it completely stopped by 3pm Saturday. Less than 24 hours. It started again this morning around 9 and stopped around 11 am again. Today is day 3 or so I think. My periods never start and stop like this. Any advice on what I should do. I am supposed to start clomid today day 3-7. My dr is closed so I can't call. Any advice would help and sorry for the tmi
