[Rebeccalou21]

Am on cycle day 25 of a 28 day cycle, about 8-9 days before af was due my boobs started to get really tender and couldn't even lay on them on bed and going up and down the stairs was horrendous, then veins started to become very noticeable, even all over my chest this never usually happen, then started to spot on cycle day 24 very very light barely even noticeable, put on a pad just incase but was nothing all night till this morning I felt a little gush (TMI sorry) and there was more only this time more pink not like fresh blood pinky and watery, no cramping or pains, just a few twinges here and there that last only few seconds, could this be implantation bleeding or the start of af been feeling real ******, just want this to be our month been trying since January after an ectopic in August last year
