Abnormal bleeding

So… I am going to go get it checked out so before anyone says “go get checked” I am… but just wondering if anyone as any insight on it but my breast are always sore and I think I had my period like 2 weeks ago it was 4 days which it’s usually 5 or 6 days at most.. so that was little weird and now 2 weeks later I’m bleeding and I don’t know why… I’ve been stressing a lot with moving and all I don’t know if it’s due to stress or what but if anyone else has has this happen.. Until I get checked im just going to be sitting here freaking myself out thinking it’s cancer or something and I haven’t had sexual intercourse since like July so…
