Should I go to the docs?

McKayla
So when I got pregnant with my son we technically found out when I was 6 weeks with a blood test but hcg was so low they had me come in 2 weeks later and do another to confirm. Well my period is 6 days late and I feel pregnant, but I dont want to get my hopes up because I have had several times where I thought I was pregnant. Well the smell of cooking meat makes me sick, the view of raw meat grosses me out, when im hutched over I start getting a twitchy cramp in my lower abdomen/ above my pubic, im constantly tired, and back pain. Well I took a test on the 11th and 14th and both were negative but I am not sure if its my hcg levels because I know my body produces it slowly. Do you think I should go in or is my head just playing tricks on me?
