Levothyroxine and Conception

[pinkmarshmalloww]

Hi. Has anyone noticed their cycles got shorter after starting Levothyroxine?
I normally ovulate CD14-15
But I'm starting to get dark OPKs and I'm only CD9?
I've only been on the medication a month along with high doses of VitD and folic acid as they were also low. Everything's now looking good on blood tests which I had done 3 weeks after starting meds to check levels.
Hypothyroidism was classed as "mild"

It took me 12 months on medication to get pregnant, and I was only clinically subnormal, not actually hypothyroid.

Having an underactive thyroid threw my cycles completely out of whack. They were long and annovulatory until I started taking Levothyroxine, after which they settled down to 30-33ish days with ovulation around CD17.

I can’t answer about ovulation but I got pregnant 6 weeks after beginning thyroxine, after 11 months TTC.

@pinkmarshmalloww I was wondering this. I started levothyroxine 3 weeks ago. I'm currently CD13 and usually O on CD 19/20/21 but my cm has been looking more fertile a lot earlier than it normally does. Opks are still low for me atm but I do just have a sharp rise in the normal way.

Mines usually the same. Sharp rise in one day. I haven't tested today but will be in about half hour, I'll post the results. Last month I'm not even sure if I ovulated, my period was 3 days late and lighter and shorter than normal, the cycle was a longer one than normal x

Bear in mind hypothyroid women can often have PCOS too (I do) and if you do it throws OPKs right off.
