as you can see i ovulated last week, yesterday i had a tiny bleed, also yesterday and today i have had cramps (very uncomfortable), could this be inplantation? i have also got tender boobs and the bottom of my back hurts also a dull ache in the bottom of my stomach when not having cramps you can see from the chart i am not due my period for another 9 days also i am not constipated x
