Hi.I Am 21 Years Old,female.Lately, Since 5 Months Ago,i Have

Hi.I am 21 years old,female.Lately, since 5 months ago,i have been experiencing irregular period.But since June, it keeps getting further apart by additional one week.Asides from that, i experienced lower abdominal pain on left and right side.The pain is not severe and it is constant.I also experienced spotting sometimes in between periods.Do you think it is normal since this happened just several months ago? Thanks in advance.
