Losing hope!

I'm 12dpo, I have had a few symptoms and I'm still getting negative test. One app says my period is due today and this one says I'm due in 2 days. I dont have anymore test,I took my last one this morning, but i cant seem to bring myself to go buy any more. I cant take seeing just that one line. I feel like theres something wrong with me like I cant conceive and i want nothing more to give my husband the family he wants.😞😭
