So I've been experiencing wot I think is implanting bleeding for almost a week now it's only there when I wipe like a brown gunk, af due in 6 days time , would use think this would be considered normal? Symptoms are just lower back ache , bloating feeling and biggest of all no tender breasts which I get every month two weeks before af , when do u think would be the best time to test with this brownish stuff still there?? Any advice would be great , thanx
