Pipipia you start the progesterone cream AFTER ovulation. I began 2-3 days post O, which is typical, you want to make sure it's after your temp shift. I used until my period began, but sometimes I would get some spotting but temp still high so I continued until I saw a temp drop meaning I was definitely out that month. If you don't temp, which can be a drag, just use for 14 days then stop.
Take the DHEA and CoQ10 daily
I used primrose oil a few months, but while it initially increased CM, subsequent months didn't work, seemed to decrease my CM...I really obsessed about the quantity of EWCM a lot, but you know what, the month of my BFP, I basically had just watery/wet/slippery CM, but didn't see that gob of EW that I would often get when I wiped, but it apparently didn't matter.... as long as you feel something slippery it's good.
BTW, I found temping MUCH easier to do vaginally. My alarm would go off, I'd hit the "doze" button pop it in thermometer, maybe fall asleep again, but didn't matter as thermometer had a memory, so it wasn't a big deal, just checked when alarm went off again. Vaginal is more accurate too I feel.
