Miscarriage or period ?

The ONLY way to know if you were or are pregnant is to try and take a pregnancy test or get a blood test. Either way you need to be seen by a Dr.

i kno i have to do that..
but i have no insurance and not even money
to go to the clinic..

There should be a clinic somewhere around you that will take you for free if not then go to the ER. If you aren't pregnant or having a miscarriage it sounds like something else is wrong that needs to be looked at. Either way right now I would go ahead and take a pregnancy test so you can at least know that. You should be able to go to your local health department. They should also be able to give you some type of birth control because it sounds like you are not ready or prepared to have a child. I really do wish you the best of luck and I hope and pray you are not going through a miscarriage because I have been through 2 and I know how hard they are. It is possible you could have some sort of other issue such as thyroid issue? Or many other possibilities. In th emean time make sure you are not having sex and get a pregnancy test. If you are not wanting a child make sure you use some type of birth control. Again I wish you nothing but the best.
