Should i lose weight?

Hi guys! I recently lost 20 pounds after gaining 40 once married. I’m really happy where I’m at- I’m definitely not thin or trim but I don’t mind having a bit of weight on me in exchange for getting to eat and enjoy food with my husband.

I’m 21 and 5’5. I started at 125, then got up to 165, then now have stayed around 140-145. I’m concerned that this weight might be contributing to infertility? No doctor has said anything but to be honest, I have only been for a preconception checkup after my initial weight loss (I got to 139).

Let me know- more than anything I want to be healthy and I am going to start exercising again but I want to know if I should be focusing and training harder to lose some pounds.
