After lifelong irregular periods, I had a surprise pregnancy when I was 35. I breastfed my daughter for 3 years afterward, and did not regain my period during that time. I tried some herbs off and on, but did not commit and did not see results. 3.5 years later, I did one round of prometrium (taken vaginally) that restored my period. I did acupuncture 2-3 times a week, and committed to vitex, and other herbs and supplements that supported my blood sugar maintenance, thyroid, and overall health. I saw several infertility doctors who gave me terrible odds of pregnancy (I am 39) and offered me all kinds of drugs. I committed further to charting, and used progesterone cream after ovulating. I read everything on this site and consulted with them twice. After 5 cycles, I am now 10 weeks pregnant!
