Before my period came I had 3 faint positive pregnancy tests, i had very sensitive nipples then my period came was quite heavy with cramps, so I assumed I had a miscarriage the sensitive nipples stopped. Now 4 days after my period stopped i wiped and had brown discharge, followed by blood, (dark red) I have had to put on a pad. There's only a bit on pad and when I wipe not loads. & sensitive nipples have also came back. Has anyone ever experienced this before?

Updatee*

So I took a pregnancy test today says 2-3 weeks pregnant and then first response came up a strong positive straight away although im still spotting this is the second day of the spotting
