Help. No period after removal

Alaina

Hi so I’ve only had one period that was very short and light after my removal. I got it out june 25 & had one short period in July and not since then. We had unprotected sex once but it was back in July. My so was leaving for military and it was the last thing on our mind.

Has anyone else not gotten their period after the removal?? I had mirena in for about a year. Should I take a test???
