So I took this 3 days before my period was suppose to start and I actually had started my period or maybe what I thought was a period 2 days later it lasted 4 days with a good flow but no clots like a normal period and I had little bit cramps nothing like I normally do day 4 I though it was over here comes day 5 it weren’t heavy but every time I would wipe there would be some light red/brownish until day 7 my periods are normally 5 days at 30-32 days apart this time it came at day 29! Someone please help me understand! Should I retest ??
