On dec.5 I had a short period that only lasted 4 days and was really heavy at all. But I ovaleted on nov.21 and . Had sex during that time and after dec.5. I been having headaches , my lower back been hurting a lot bad, I been eating a lot of sweets and eating a lot, its like I stay hungry. I feel tired a lot and been very moody and fussy a lot lately, my feet sometimes hurt sometimes have a few cramps that just send sharp pains. But they don't happen a lot when the cramps come I sometimes notice when I go to the bathroom when I wipe there is just a little blood but nothing bad could I be pregnant or something else.
