we have been ttc for a while now. lately ive been getting what feel like very mild period pain and i was wondering what implantation pains feel like. im not sure if this is what im getting or if it is my period again. my period is due in 9 days but i dont usually get cramps until i do come on. im trying not to get my hopes up and thought maybe would do a first response test. does anyone have any experience of these are they reliable or should i just wait and see if im late.
