Overweight and trying to conceive

I am just looking for some advice not judgement, I have been overweight my whole life despite when I was younger going to dieticians, my parents watching what I was eating and ensuring I was constantly excersising there was no improvement. When I was a teenager I tried every diet possible then when I was older and started driving everywhere and working in an office (and being in love) the weight piled on even more. I eat less than other people around me and I still feel that if I look at food I put weight on. I had problems when I was on the implant as I had a constant period, I came off that a year and a half ago and have being trying to conceive I am really struggling. Most worryingly my periods have now became really long as in I am currently on day 61, I have taken multiple tests and I don't even have a hint of a faint line. This happened previously this year when I skipped a period and I went to the doctor I was told that was normal. I feel like if I ask for help to conceive I will just be told to lose weight. To be honest I am not bothered about losing weight as I spent so many years trying to please other people by losing weight but now I am happy in me and I was happy enjoy to get married at this weight it is not a priority to me however is this really stopping me getting pregnant? Would I still be able to try clomid being overweight? I would really appreciate if other overweight ladies could tell me their experiences thank you! X
