Dear Doctor, I Had Three Times Abortion Before 2013. Since

dear Doctor, i had three times abortion before 2013. Since 2014, my period flow is very light. it only took 2 days, but the period comes regular. last month, i found out my period flow even less with brown blood, only last 1 day, but it's regular period. i m so scared, i want to have a baby in the next year as i am 38 years old already. so what treatment shall i take? or shall i be worried?
