Hi I don't have periods haven't since I had my first child six years ago and now I have been told I have polysistic ovarys now I have had back ach and very bad boob ache I canrt bare to touch them or lie on them thy are hurting so much but I have had negative tests for three weeks with my two other children I new before I was four weeks pregnant but now I just don't no what to do I have moved and I'm not close to my new gp so I don't want to go rushing to see him .

Since you can't use lack of periods as a sign of pregnancy, only other options would be to keep trying tests, which can get pretty dear, or see the new gp. Hopefully they will do blood work given the fact that you have already done some urine tests.
If it is a concern, you can also see about options for trying to regular your cycles.

Thank you I am just worried I want to be pregnant it feels like its never going to happen but I have been for a scan and thy have said my coil fell out over the last year I fell pregnant so quickly with my other two without my periods but since having the coil my body has been very different now like I say got the sore boobs back ache my boobs areunbareable but have been back and forth o docs don't want them to be sick of me lol
