I am 9 dpo today! At 8 dpo, i had NO symptoms at all EXCEPT for yesterday night Valentine's day, I went to the bathroom after being with DH, and my pantyliner had a snot like strip og pink, i was happy but trying not to get my hopes up! so today i put a panty liner in at 7:00 am and waited till three pm and it was a little more than last night not really watery but it was brown with a little pink i changed my panty liner and now i have a strip of pink, is this implantation i am also haveing mild cramps, though out today! And my boobs are JUST NOW starting to get a little sore! I have been TTC for over a year now and have never had a sign of ovulation! till this month, and now im having spotting which I have never had either! what do you think?
