What now?

My husband and I have been trying to conceive now for 15months with no success, so far. I have been using clear blue advance prediction kits to track my ovulation. Haven’t tried doing body temp yet, did anyone find this technique more effective?

We are 29 years old. We don’t have any pre existing conditions and I am as regular as clock work. My husband and I are both overweight and have figured that could be a major factor.

Any tips would be great :) xx
