Hi all. I am hoping to start DE treatment in September. The month before I will be doing a mock cycle. This will start on day 1 of my period with a dept injection. The thing is my periods have completely changed in the last few cycles! I am now CD41 and still no period! In March I had 2 periods in the one month. I am 43 and likely perimenopausal. What happens if my period doesn’t actually arrive…does anyone know how I would then start my mock cycle? This is stressing me out!!
