Still waiting for her to come!

I am now 6 days late. But I have been feeling sick, stomach aches, major head aches, back aches, restless, yet so tired, I am on that giving up stage. I miscarriage in march and we have been trying soooooo long. I had bright red blood very little this morning now it's turning brown and very little. I usually know I am prego when my boobs are sore.. i am so scared I may not be. I wish a would just come or I am just prego. . I feel like I am being teased. I also took 2 prego tests in the last 6 days they both had a bfn!! I am always on time to the day!! I am freaking out.. this will be my last child my husband's first and my rainbow baby.. please pray for us and hope baby dust worked!!
