    Default metformin and cycle length

    i have been on metformin for about 3 months. my cycle has always been about 25 days long, even before taking metformin. taking it has reduced how long i bleed for, but cycle length has stayed the same. so far, this cycle is up to day 41 and showing no signs of my pd starting. is this a normal metformin side effect, or could i possibly be pregnant??

    Default Re: metformin and cycle length

    I've been on metformin for a year or so now. It hasn't affected my cycle at all.

    ok , i have done a home preg test, but was negative. so im guessing probably a side effect..?? has anyone been on met for a long period of time and had this happen, or know any reason for it?? im only taking metformin, not any contraceptives, so from my understNding it shouldnt happen.plesse please, if anyone can help it would be great. docs havent been very useful to me on info about pcos so will only go to them as a last resort.

    Hello! I have just joined but feel like I should reply as I had absolutely no idea about metformin when I started on it! First of all what dose are you on?
    Me- I have been on it since mid August, 1000mg, for PCOS, and was pregnant by late sept, so pretty quickly after 2 years TTC!- that resulted in a missed miscarriage 5.5 weeks ago and I have stayed on the metformin (which is another debate in itself about whether to stay on while pg) and now I have possibly found myself pg again without having had a period since the mc and d&c (to be confirmed with blood test results on Sunday).
    So, in answer to your question, the metformin should not be making your period late, unless you are on such a low dose that it isn't working, or you are pregnant... My cycles stayed the same, 29 days. Are you sure you have been ovulating? And have you previously tried clomid? Sorry this is so long!!

    I'm on 500mg twice a day. We have been ttc for about 2 years aswell, no luck at all.
    I wouldn't have a clue if I'm ovulating our not, i don't know how to tell.
    My docs won't put me on clomid until i loose weight (supposibly anyway) they say clomid doesn't work at all on people over 100kg (I'm just over that, but have lost weight since starting metformin.

    I'm surprised that your dr hasn't put you on a higher dose- at one point I was on 1000mg in morning and 500mg at night, ad that's what I got pg on- the higher the dose the more weight you will lose and it should also fix your pcos up a bit- my understanding is that pcos is insulin resistance and the side effect of that is the cysts- therefore metformin sorts your insulin out as its a diabetic medication, then the cysts go down and you become fertile. Does that make sense? I'd ask for a higher dose if I were you- if you're definately not pg

    I also forgot to say that I was on clomid for 6 months and it didn't work for me, it just made me really depressed, like a different person, but everyone is different! Also use the ovulation predicting kits or you can ask your dr for a test to find out if you're concerned

    I don't think what your dr said about the clomid not working on people who weigh more than 100kg is right. I was close to 130kg when I started taking it as I have PCOS and it helped me ovulate regularly. I took it for 5 months before I got pregnant with dd2. With hard work and persistence I am down to 114.5kg and falling.

    I don't know but maybe it's time for a second opinion??? Yes losing weight will help your fertility but it isn't always that way for everyone.......

    Best of luck
