did some googling and this is what I found
the day you found out about the loss is not a benchmark, nor is the day you began bleeding. The actual hormone change begins to take place either during the D&C or when the placenta pulls away from the uterus during the natural miscarriage, which is usually when the cramps and bleeding are at their worst. That is Day 1 of the recovery but not Day 1 of a new cycle
The most common recovery goes like this:
Your bleeding will taper off to spotting within a week, and maybe random spotting will continue for another week. Your hCG drops steadily, usually hitting zero during the end of the spotting, or about 10 days after the miscarriage or D&C. When the spotting ends, you will get strange symptoms. If you use a fertility monitor, it may say you are ovulating, but you are not. You may see lots of cervical mucus coming out, sometimes still brown or yellow, but it is not a fertility sign either. In fact, most of the time, you will not ovulate in this cycle. You should not be trying to get pregnant, either. For why, visit the trying again section.
Some women find they have mild pregnancy symptoms, or little ovulation cramps. Many many women think they could be pregnant, because strange things are happening and their period is "late" (although almost every post-miscarriage period is late.) These symptoms are due to the body's attempts to regulate its hormones again. It may kick into gear right away, and you will get a new period in four to five weeks, or it may struggle a bit, and the period will not come for seven weeks. If you chart your temperatures, they will be all over the place. This is all perfectly normal and expected. Eventually your period arrives and can be either light or heavy. There is no "normal" right now.
Hope this helps
