A lot of the same symptoms can be caused by multiple things, this is why there are so many answers. Unfortunately that make dr's testing and diagnosing vital. I'm unsure of your specific symptoms but the first test is always a home pregnancy test. These can be found at dollar stores- and yes they are actually accurate. If you can, try to find a walk-in or free clinic they might be able to do some of the other testing for free or reduced price.
i see lots of people with the same symptoms and not a whole lot of answers. some of these posts say "i will post when i find out more". where did those people dissapear to? a lot of them say i went to the doctor and there were no results. I have no money and can't see a doctor unless i go to the emergency room. that is a lot of waste of other peoples time and money. But if it drives me insane then i will have to do it. its only been happening to me for 3 days and i'm already about to scream.
Better to do a HPT ... Hope that helps
It's quite possible, especially if you've had unprotected sex in the past month. I suggest you take a home pregnancy test with your first morning urine. The morning is best because it's most concentrated, and therefore most accurate. If your period still hasn't come by the end of next week and you get a negative test you might want to go into the dr's for a blood test.
Keep in mind that many things can cause "early pregnancy symptoms". Anything from stress to meds, so do your best to remain calm until you know.
