Just started oral progesterone from days 10-21 last month and also started taking half a tab of metformin twice a day. The last year my periods have been off and weird so my Dr wanted me to try and regulate them before we started trying.
My periods have always been really heavy. Like soak through pads type heavy and after having my kids add in tampons don't stay in and blood clots. Because they are so heavy I've been too afraid to try a Diva Cup even though I know they would lessen them. I do use cloth pads at times and they are definitely less but not enough that I fully feel comfortable with them 100% of the time.
However this is my first period since being on the progesterone and it's so light I don't even need a pad at ALL! I have one just in case as I keep expecting it to get heavier but besides a bit of spotting in the morning and one small amount of "flow" into the toilet in the afternoon it's almost like I don't have it.
Is this from the progesterone? The rest of my PMS symptoms have been less too. I'm less angry, way more emotional and have only had a few cramps.
