Trouble TTC

Can Metformin and Progesterone cause a false positive on an OPK?

Hey there!

I just started my metformin Friday and progesterone last night, when I did my OPK it was positive. I was wondering if that could possibly be accurate or if the two pills caused the positive?

Thank you for the help! :

  • I have PCOS and get false positives on OPKs.  RE told me it just happens for some people and I am one of them, thus I can't use them - you might be the same.  I think it happens more in people with PCOS.

    TTC #1 Since 7/2011

    Me: 30, PCOS with anovulation
    DH: 38, Low Morph & DE
    Rx: Metformin 500mg

    Cycle #1: Clomid 100mg + Ovidrel = No Response, Canceled
    Cycle #2: Clomid 150mg + Ovidrel = No Response, Canceled
    Cycle #3: Clomid 150mg + Follistim + Ovidrel = No response, Canceled

    Cycle #4: Femara 7.5mg + Gonal-f + Ovidrel + IUI = BFP!!!!

  • Thank you for the response, I too have PCOS, I am taking these meds to treat and help with having a little person. I figured it might be a false positive, as I haven't O'd on my own in some time.
  • You should probably ditch the OPKs and start charting your BBT. OPKs and PCOS don't play nice together.

    Good luck.

  • I have PCOS and ovulated a couple of times a year if I was lucky.  When I started metformine alone I ovulated in 6 weeks.  It's definitely possible it's a true positive - but it def could be your PCOS playing tricks with your pee (although - I'm not sure you're gonna O while on Provera).  I'd BD just in case.

  • Can I ask a stupid question, where can you fun information about charting? I want to make sure I am doing it properly.

    I feel a little in the dark with everything! My OBGYN did the necessary testing to determine that I have PCOS and then had her nurse call to tell me I had a prescription waiting at the pharmacy. I have been trying to google and learn more on forums like this, but I am just so lost.

    I want to find a new doctor, I am just not sure where to start since we just moved. I also, just feel a little uneasy talking to friends about everything, because they just got pregnant. It almost makes me feel bad...

    Sorry to unload!

    Fertility Friend is a great app to learn charting. They have tools, courses, andmy personal favorite endless hours of chart stalking. You can access through most anyones siggys.

    This is a great place to ask questions and bounce things off people. But, if you have been trying for less than one year, TTGP is probably the place for you. GL!
