Me and my partner has been trying to conceive for the past year. I'd been tracking my periods for a few months and this month I was 10 days late for my period and getting symptoms like abdominal pain and mood swings. I took a test and it was a negative, 3 days ago I began bleeding lightly and pinkish in colour and only when I wiped so i assumed it could've been late implantation bleeding, the next day it was slightly heavier and small clots alongside stomach pain. I have been bleeding for 3 days now and I have stomach pain. I have took another test and still negative. Could it just be a late period??
