I am 36 years old and no children. A year ago I use progesterone cream, the 15th-26th days. My menstruation cycle is 26-day. Is spotting before menstruation, lasts up to 10 to 14 days before menstruation. Because of the progesterone cream initially improved, reduced bleeding for 6-8 days. Over the past two months my condition worsened, but I do not know why. I'm afraid the wrong dosage. The last month I increased the dose of 3 g / day, but have already started bleeding at 18 days and was strong enough. I would like to ask exactly which days to use the cream? How many grams per day to use it? Already I'm very upset about this. I want to get better, but this condition did not improve. What more can I do?
