Aww I understand the confusion, especially dengan irregular period tu memang susah nak predict! Dari yang you cerita, kalau ada double line even kalau samar-samar, kemungkinan besar ada something there, CP (cervical position) changes boleh jadi sign awal pregnancy juga, so it's actually possible untuk get those symptoms and then turn out pregnant. The best thing is to do another test in a few days when the line might be darker, atau go see your doctor untuk blood test which is more reliable especially dengan cycle yang irregular macam yours. Fingers crossed for you!
