hey guys .. im new on here .. ok so my boyfriend and I have been TTC for 14 months with no luck ... my periods are like clockwork for 4-5 days usually with a heavy flow but this month was TOTALLY different , [ sorry if tmi ] my period arrived 2 days late , started off spotting then a sticky brown like discharge then went to a light flow [ I needed a tampon ] lasted a day and a half and now ive been spotting pinkish/brown for the last 4 days ... today I woke up with nothing and then this evening spotting started again??? ... has anyone had this experience??? this has NEVER happened .. could it just be old blood?? or am I experiencing implantation bleeding??
