Only a doctor will be able to give you the correct answer but I imagine either you arent pregnant and those symptoms are something else or you are a very rare case where the tubes become untied, or even ectopic pregnancy. Either way the last two are rare , only your doc is going to be able to give you the right answer. I'm certainly no expert.
I am no expert either. But I have four children and know the symptoms well. I have also had what you are talking about in your question. I was told, and there is no pretty way to put it, that it is gas. Gross I know but still the same. There could also be some hormones that are off alittle. Might ask your Doctor about that as well!
To your comment back to me... Have you asked your Dr. To check your hormones, Those things can do some crazy stuff to a woman's body. I have four children, 10 year old girl, 5 year old boy, 3 year old girl and 1 1/2 year old boy. After our last one, things were changing in me too. If you have not already get your hormones checked. It is very rare to get pregnant after your tubes are tied but maybe you should have that checked again too. Mistakes happen all the time. Good luck, I hope that you get some answers. I don't know you but let me know what you find out. If you want, you don't have to share your personal info. With a complete stranger.
I sex in 4th of april 2009 and period date is 8th of april 2009. So how I know I am pregnant.
Do what ever makes you happy and ignore what other people say if they are you true friends it doesn't matter, if they are not why care...
