Need advice!

My period was meant to start on 27/3, on the 28th I started having a dark brown bled no red at all, got lighter and light over 4 days then nothing now! Haven’t had nothing since 2nd of this month, I’ve had a light white discharge, only when I feel up there (tmi!) I’ve had no cramps while I had the brown bled, I’ve had a few sharp pains on one side after the brown stuff stopped, this had never happened before! I always get a red flow, I’ve had brown blood for 2 days max then the red flow comes Has anyone had this then ended up pregnant?? I’ve done test but bfn! PLEASE SOMEONE GIVE ME ADVICE
