I Give up

I just don’t get it. I’ve spent so much money on buying test just to see the answer negative. I had faith but I feel like giving up. I think it’s a positive and it’s an not a positive. My periods are on track I ovulate regular I’m confused. I workout I eat healthy I take vitamins, what could it be? My partner and I been trying for a year then stopped because I can’t keep hurting myself. I see everyone with their positives and I can’t even get a faint line. My friends have gotten pregnant so many times and I’m just sitting here left out and she doesn’t even try. I cry myself to sleep because of this issue. My insurance doesn’t cover infertility. I’m sorry to be a Debbie downer but I don’t know what else to say. I even tried the preseed and pills.
