I've been getting quite a lot of dizzy spells. Sometimes to the point where I black out momentarily and have to clutch the wall and wait till I feel better. I feel weak and tired all the time and often feel really cold too. Is this normal? Or is there something wrong with me? Last night when I went to the loo I wiped and found some fresh red blood (not a lot) on the paper. This happened twice but since then nothing. Nothing on my undies neither. I've got cramps, but I've been having these since 4 weeks. Help.
