Is it normal to get your period twice in a month?

Taralee_21 • Sunshine ☀️ mix with a little hurricane 🌪

My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> told me that I should expect another period by the end of this month,which leads to early February and another period late February which runs over to March and by the end of March again

This happened already but I was 13, and it was my hormones. And now, Since lately I had sex 2 days in a row. Could this triggers it?

Should I be worried ?
