What are all your thoughts?

Hi all, I'm due for AF today. Yesterday I had some pains down in the pelvic area and late afternoon I found myself in the toilet head over the bowl a fair few times!! I have been extremely tired the last week and today is no different, it's l happening again. I have lost my appetite to eat and have found myself having strong boggling headaches on and off! I tested over the weekend and it was BFN but I'm so tired of getting these that I may just wait some a few more days to test! Maybe I could be coming down with a bug ?
