What are your symptoms before you get +ve result?

Hi all mommies! I need to ask for your opinion, I'm having cramps for almost a week now with sticky white discharge (sorry tmi), increase in appetite, migraine and backache. Bila saya check upt, it always come out -ve. Now I'm very sad. I have irregular period but even when I'm about to period or ovulation, I never had such symptoms. Dan saya dah consume folic acid about two weeks now. Adakah ianya effect dari folic acid? or has anyone pernah mengalami situasi like that macam saya then end up got +ve? I hope I'll get good news as I'm already 30 and just got married two months ago. Have a good day, mommies!
