Thanks so much, I did not know this at all! I had made an app with my Doc this week as I was so confused. After trying 200 mg utro for 12 days orally and vaginally, terrible side effects. Then I tried 100 mg utro for 25 days of the month, did this for couple of months but felt too sleepy all the time, then tried 100mg for first 7 days of the month but didn't get a bleed, tried this for few months, had 2 months approx off utro just used the gel, had a vaginal scan last month and lining is thin and is ok, this month I started utro 100mg, starting on the 15th day of a 28 day cycle and wanted to use for 12 days to see how I get on with this regime, however on the 6th day I started bleeding so last night (7th) day I stopped utro and I am now having a bleed. I will start this regime again on the 15th day of a28 day cycle and am keeping notes in my diary of it all. Used gel this morning all over inside of arm and shoulder rubbing well in, but still very hot, I always rub on my arm. I am slim built and about 8stone, I use the gel 2 pumps a day. Thank you so much for answering so quickly and for welcome.
