Hi has anyone had a similar experience? Had sore nipples and tiredness, pure exhaustion for 3 days now just light headed. Don't normally get like that. Have had a very light bleed which seems like old brown blood. Not enough to fill a tampon just like the end of a period. Seems to have stopped now. Hoping this is implantation?! Have had twinges and some sharper pain. Lasted tested 11dpo in evening and was negative. Just going to wait and see and test perhaps Saturday morning.
