Two Periods in One Month.

I had my period on 8/8/17-8/14/17. I engaged in intercourse the day after my period. My hubby fell sick so that was the only time we had sex. It is now a week later and I'm bleeding again! I had my daughter 6 mos. ago my periods have came either 10 days only for 2 months or on time for the most part. I know it's probably possible, but should I call my doctor or just think it's my periodx2!
