I started on a combination of Armour and Synthroid about 6 years ago, keeping my TSH at about 1.5. Subsequent to my diagnosis of Hypothyroid/Hashimoto, I was diagnosed with PCOS and referred to an Endo. I took Metformin for about 6 months the first time, stopping because I did not like the side effects. When we decided to start trying to conceive(May 06) I agreed to try Metformin again. I was on it for 3 months prior to attempting to conceive my daughter. We conceived the first month we tried. I stayed on Met through the first trimester and also used progesterone cream as prescribed by my Naturopath for the first trimester.
Since my daughter was born(Feb 07) I have had a 'regular' cycle. Up until about 6 months ago it varied from 28-33 days in length and I could tell when and from which ovary I ovulated. For the past 6 months I have had regular 28 day cycles. My other hormonal side effects have also diminished since childbirth(PMS, Acne, Bloating) My daughter also exclusively breastfed for the first 8 months and only had breastmilk or water until she was 3+ years old. I think pregnancy and breastfeeding really helped regulate my hormones.
We are going to try to conceive again this Fall and I decided that I am going to go back onto Metformin again. I am a bit conflicted because I have had such positive changes(the only thing that hasn't changed is my excess weight) since having my daughter. I wonder if I really need the Met to conceive again and prevent miscarriage. At the same time I know that I had a positive outcome while taking Met before and want the same outcome for #2.
At any rate, I guess I am here to share that Met worked for me with #1. I wish you the best as you try to conceive again.
