So myself and dh have been trying for over 3 years now :-( and have done Ivf with no luck, we are doing herbs and acupuncture while we save for next round. My acupuncturist/herbalist told me to take temps to work out when I'm ovulating and it turns out I am ovulating quite late the thing is according to my temps I ovulated on day 18, it's now day 23 and I have just started spotting for my period! I also had a temp drop! This is ringing alarm bells for me because I seem to be having a super short luteal phase!! Does anyone have any tips on this? Could this be the reason I have had a chemical pregnancy? Please help!!
