not sure if its the right place

hi i am 22 ,for the last 3 and a bit months i have been bleeding off and on now i have two children and my youngest is 19 months old before her my period was fine 21 days apart 4 days long, now im spotting evry other day in-between my 8 day apart bleeds which last 5 days or more. nothing else really wee a bit more bloating pain in ovary's bleed if i have intercourse and after for 4 days. bleed is like normal period medium blood spotting is up to 3 times a day. also if i check my cervix i bleed quiet bad 3 seconds and my fingers covered in blood even if there is no sign of bleeding. am worried.
im not on any birth control since bub was born and no medications not stressed well no more that normal. just worried and slightly frustrated as you could imagine
