Im so sorry you are feeling like this, I know how frustrating it is. We just finally managed to get out BFP on cycle no 18, I said every month I was giving up, it takes over your whole mind, doesnt it?! Hopefully this one sticks, Im only just past 6 wks and have had a couple of chemicals in the past. Anyway, I just wanted to say good luck and that I had great success with using CoQ10. I had been taking it along with Maca for the last few months as well as feeding it to hubby, and upped the dose for me to 600mg this month. Within a month of starting it we got a bfp but it was chemical, at least it was a sign that we could actually get pregnant though so although it was upsetting it gave me hope IYKWIM. I had heard it can take 3 months to take effect and it certainly seems to be the case with us. We are both 43 and were really just about to draw the line and give up hope. It is a bit expensive but worth a shot maybe? A lot cheaper than medical intervention for me, was my justification.
I didnt temp either as I knew it would make me crazier, but did monitor CM and used OPKs. After all this time and loads of TTC prior to Mr 2 I know my signs quite well - do you think dumping the temps would maybe help?
All the very best, chin up xxx
