Obese and TTC

I'm 5'1 and recently learned I am 220 lbs. Wondering if this is why we haven't conceived yet even though I have a regular period and ovulation schedule. I want to lose weight desperately but I feel like I don't have the time in my life to plan healthy meals and exercise. I work full time and get home and have a million things to do and a million places to be for my 6 year old. Ugh
