I don't know what to do, so confused. Last night in work I had lower back pain to the point when I was bending down I was trying to support my back so when I got home I took a test and it came back negative.. :/ I decided to take the other one on morning urine and that to came back neg. But all I've done today is be sick, my period is now 9 days late the last one was 28th of January and that to was 5days late. I have no clue what's up with me, my partner is in the army and he's currently away on exercise until next Friday so I'm pretty much on my own with this, I don't want anyone to know because it would build my mothers hopes up she would love a grandchild. Do you think I could be pregnant and its just not showing up on tests yet?
