I'm already 9 days late, i have taken 3 at home pregnancy tests and they all read negative. i have been having lower back pain and abdominal pain..i thought it was because my period was coming but it hasn't came. i get really tired and lately i keep waking up at night, don't have any pregnancy symptoms so I'm not sure whats going on.can someone give me advice?

It has been two months for me and I have been experiencing the same thing also. I took one HPT and it came back negative, also. I am a tad bit worried. I have frequent urination, I sleep alot and wake up at night. I try to sleep on stomach but i feel pressure so it is uncomfortable. Help?
