weight question

Ew
Ok after mos of no luck my period being irregular blood test normal my doc can't find nothing wrong but the generic things like weight stress etc. i kept brushing it off because I didnt think I was overweight maybe because it's in the right places but I got on the scale recently and I am almost 200 lbs 😩😔 that's when it dawned on me like ok there is no way I should weigh this much at 5'2 so I have decided to loose 20 to 30 lbs I know it won't be easy but I am committed to it because it made since this is the most I have weighed so I feel like loosing weight should do the trick hence reg cycles again and ovulation back on track anyone else loose weight and got pregnant?
