What should I do, ladies?

Starting 7/23 I spotted off and on until Monday, 8/1. I didn't spot every day, but when I did, it was brown of pink/light red. The second two day of bleeding was bright red but died off after 1 day. It was like my period. I was due for my period 7/30 but she never showed. Since Monday, I've felt nauseous off and on. Today it's been since 5am...I will feel fine and decide to eat, then as soon as I take a bite I feel like I'm going to be sick...what should I do? I've also been very moody, and my husband and his best friend pointed that out to me. Like, I got mad because my hay and couldn't tell me where the remote disappeared off to, and I was seriously mad at him..
