I have had brown spotting instead of my last two periods (the second one was about a week earlier than my expected period), however the hpts have been negative. I have never ever experienced "periods" like this, especially not two in a row. I have also been extremely fatigued, swear my boobs are getting bigger (but not sore), and I have been peeing a lot. But those could be stress and I drink a lot of water. I would technically be around 8 or 9 weeks prego if I actually am. I would go to the doctor but I don't have the extra money right now and I don't want to go and just be told I'm fine. Has anyone experienced this or have any idea why this is happening? I am going to call on Monday and see if the DR has any suggestions.
