Karina

If i go base on my first day of my last period im 6weeks pregnant but i this pass weeks i experience brown discharge and this pass 2 days I experienced alot more brown discharge to the point to change my liner pad but it wasn’t blood it was more like maroon/brown blood and I also been experiencing cramps on my stomach, i just wanted to double check if someone had experience this before and if this is normal? TIA!
