My husband and I started trying to conceive two weeks ago, this would be our 4th child, 3rd pregnancy. I do not know if I am pregnant but I feel like I am heavy in my bottom I am cramping a little it doesn't really hurt at all and it's not all the time and I am bloated. I've never done this. I have the over welding sensation that I am pregnant. Of course I took a test and its negative. Any thoughts???
