Could I be? Or is it in my head?

Kaitlyn • I`m 19. Recently had an ectopic miscarriage and praying for a miracle
Okay so my husband and I have been trying for over a year now to conceive. We were successful last summer but I lost my angel. Now, I am constantly tired, nauseated most of the time, headaches like crazy, and discharging out the wall!! My last period was two days then I started spotting for 2-3 days after that. I'm so weak like I don't have the courage to get up. It's like my body's just worn out all the time! I crave salt!! French fries are all I wanna eat now! I need your help or some advice..
