Im a UK resident currently on a working holida visa in Australia and I dont know anything about the medical system here. So was wondering what to do. I thought I might of been pregnant as I normaly have a very regular 28 day cycle and I have NEVER been more than 1day late. I havnt benn on birth control for over 8 months. but this month I was 2 weeks late. I also had some symptoms- I felt sick quite a lot, sore breasts, I had a lot of headaches, really tired and urinating more. I took a few home pregnany tests in that time but they were negative. I finaly got my 'period' but it was really different to my normal one. It was a lot lighter and it was also a lot darker in colour and I had no pain at all whereas the last 2 months its been very painful for me. I now has a weird dicomfort ache/mild cramping on the left side of my lower abdominal area. Im still getting headaches, and I have pain in my lower back and sore left shoulder blade. I feel sick and also feel tired and sometimes some dizziness. I looked up some symptom online and was wondering if there could be a large cyst on my ovary or if I could be an ecopic pregnancy. Dont know if its just me worrying. Thank you if anyone can help.
