I am recently going through an extremely weird, confusing situation. Okay well I had ovulated a week ago and exactly 6 days after I received what seemed to be my period however the night before my stomach hurt extremely bad and I was in awful pain, the very next morning I noticed I received a spotting of my period and it has been 4 days now and I have a mild period but I'm extremely scared if I had a misscariage or is this is just a normal pregnancy? Please help me,PLEASE! Anyone just please helppppp :/

I just had my period for 3days, started it on (Jan.10) ended on (Jan.13)
Can someone please help me out I find this extremely weird?
