I have been having nausia, headachs, darkened nipples, lower back pain. I have been waking up in the middle of the night to throw up. My period was late but it was barely there. My breast are heavy. I have been having light cramping. I took a pregnancy test that came up nagative. But could I be pregnant?

It is possible. When did you take the pregnancy test? If it has been awhile, try another one. When would you be due for your next period?

Have themdo a blood test not all pregnancy tests arre right
