When I took a pregnancy test from Wal-Mart it said negative. What does that mean. I'm nauseated without vomiting and boobs and nipples are sore. My head hurts and my back hurts.

How long since your last period? Did you test with first urine of the day?

Boobs hurt most women when their period is due...

DId you take the test when you first woke up the first time you peed in the morning. If not.. you have to buy another test and wait until tomorrow morning.

Also if you are not already at least 2 weeks late... it might just be too soon to expect a valid result.
