Ok here's my problem and I hope I don't sound stupid. I have 2 children and they were both planned so I knew the symptoms. I'm 26 yrs old and my youngest is 3. I have been on bc and have never been irregular. I was suppose to start my period a week an a half ago. The day it was suppose to start I had some spotting that was light and only lasted a couple of hours, with light cramping. After those couple of hours it didn't come back so I waited about 3 days and took a test which came out negitive. The only other signs I have had are fatigue,constipation,nausea that comes and goes,major moodiness,and my lower abdomen feels strange. It feels like I have been holding pee in or like I have a gas bubble the size of my fist. It only bulges a little that I can feel when I rub my hand over that area. I was just wondering if I took the test too early or if it's more serious. Please any advice would be great. Thanks!
