When can I expect AF after miscarriage?

Brittany • Pregnant with my Rainbow Baby🌈💜
My husband and I have been TTC for a year and have been going to the dr and did my first round of clomid mid feb. We got our first BFP March 16th and were ecstatic! Unfortunately I miscarried at 6w. The doctor followed my levels back down to zero which only took about a week. We are wanting to get right back to trying and have a new prescription for clomid 100mg this time but are waiting to AF  to come. I usually PMS pretty bad but am having no symptoms. I was supposed to start today but I don't see any signs for the near future. Just wondering how long it usually takes after miscarriage?
