Another pair of eyes

I need some help. I started to be depressive and anxious. We try to conceive for 8 months now without positive results and with much more stress. I am disappointed about me because the baby isn’t appeared yet. I try to don’t think of any of us can have infertility problems. With my first child I tried just for 3 or 4 months and he is now 5 yo... but we try for the second... i started a treatment with folic acid and vitamin b12.... from the last month I’m feeling sick... i have some cramp... backache every day... in the last period i have some nausea and cravings... from 2 days ago and have a sore nipple.... and in the last week i eat from when i am woke up until i get to sleep.... i these 8 months i took a thousand of pregnancy tests... what i need to do? What i need to know? If anyone can give me any advice i am very grateful...

And these are my tests from today:

I hope I do not have line eye😭
