Giving up hope 😪😭 please help!

I’m starting to give up on getting pregnant and thinking it is never going to happen. Everyone around me is getting pregnant, except me..

We’ve been trying for 14 months. I think my weight is effecting it. I weighed 230lbs, but I’m down to 196lbs now. Has anyone ever lost weight then got pregnant?

According to the app I’m suppose to start my period today, but sometimes it’s a couple few days off (my cycles are from 30-34 days) I didn’t get cramps like I usually do before I start my period, but I just know I’ll start. I took a test this morning and it was negative. If I was pregnant shouldn’t it show up by now?

I do know sometime I ovulate late, by like a week sometimes.

Any tips are greatly appreciated!!

Thank you!
