Period is late

Mackenzie
On birth control. Skyla iud. I've had periods every 3-4 weeks with this both control. Havnt had a period sense january 17th. No signs of Aunt Flo. No sore breasts. Just bloating. No cramps either. Usually I spot about 2-3 days before my period. I took a test, the Walmart cheapie and I'm pretty sure it had an indent.
