weight and infertility

Does anyone know how much overwieght you have to be for weight to be a cause of infertility.. im 165 and 5'5' with a medium frame.. we have been trying for almost a year with no success.. i know i am capable of being pregnant cuz we are trying for number two.. i know i ovulate every month cuz ive been taking opk. its just so frustrating.. the only difference from when i got pregnant then and now is im about 20 pounds heavier..

I am your height and got pregnant with my first child at 180 and I have gotten bigger since then and still had 3 more kids. I don't think it is your weight, the time will come for you  

I wouldn't think only being 165 would have an effect. I do know that A LOT of women get pregnant when they start a new exercise routine though, maybe you should try that! Also, it could be your SO, not you.

I weighed close to 180 when I got pregnant and I am only 5'2"

Im totally going to try the exercising thing thats one thing i havent tried yet.. i dont think its my SO cuz he has fathered 2 children.. but it could be

I have PCOS and weight affects hormones/fertility for sure. I was told by 2 doctors that I would need drugs or IVF to get pregnant. with both of my now kids, I had surprise pregnancies with no intervention a couple of months into exercise/losing weight routine.

If you are getting positive OPK's then I wouldn't say you are struggling with infertility...but just being overweight a little could affect ovulation. I have many friends who struggled to get pregnant and as soon as they lost a little weight they got pregnant.

It was weight for me. I wasn't menstruating OR ovulating. I lost 56 pounds in 5 months and became pregnant two months after.
