Help my body is driving me nuts!

Crystal • Hello everyone I am new here and thought id join for support. I currently have a 4 year old little girl, ready for 2nd
So period was due 3 days ago. Yesterday I wiped and had brown discharge only a few times. Today I woke up and wiped and saw bright red blood with a blood clot. Thought it was my period but only lasted an hour? Any advice ladies!!!
