Incredibly Confused!

Jessica
I've posted previously about this issue, but I'm currently 2 months late on my period and I keep getting negative pregnancy tests! The past week or two I've been getting "mock pregnancy" symptoms. I'm not sure if it's the real thing or not. I'm craving salt (as a matter of fact I just had a cup of chicken broth), urinating frequently, light cramping where I get period cramps, and a lot of white discharge, frequent headaches, some diarrhea, some constipation, and mood swings. I also began to gain some weight which is super atypical for me. I lost a child to miscarriage almost a year ago and I feel like I did when I was pregnant with him or her. Any insight? I feel so alone! I've reached out to my OB and she said to wait another week and test again. I'm so nervous and confused. Words of wisdom?
