I have been having odd symptoms the past week. I am about 10-12 days PO, but I havent kept track of it too much. Had nothing but BFN's up to last night. But the past week been sleepy. Then Sunday onwards I have had stomach cramps low down coming and going. Yesterday all day I felt nauseous and very dizzy, watery mouth like I could have been sick and on the train home felt almost travel sick. I had a horrible horrible taste in my mouth, I wouldnt say blood but I would say metallic, almost like sucking a rusty spoon. It was horrible. I ate my dinner fine. But then afterwards felt sicky so went to bed at 9, I have been going to bed early lots. I have had a slight lower back ache, but this has come and gone, twinges. I havent really had sore bbs really, but even when I am on I dont. I am about 3 days late for AF, but did HPT last night from Boots and BFN. HMMMM!!!!! I dont know, I feel okay today apart from headache and odd back twinges.
