Ttc #2

My husband and I are trying ttc #2 but im worried my weight will get in the way (and thyroid issues even though im on medicine) ..i know I need to lose weight regardless but its so hard. I am currently i think 8 or 9dpo and i got a bfn. Im worried this will either take forever or not happen at all...it doesnt help our sex life isnt as active as it used to be...i feel like so stressed already 😣 ugh!!!
