Hsg/hysteroscopy/ removal of two polyps

In mid April I had a hysteroscopy, hsg, and had two polyps removed. I missed my period and I’m on day 34 I believe now. Nurse says hcg is negative and progesterone is at level 4. Has anyone missed period after these procedures. Waiting to hear back from doctor. I’ve read another comment on another site where this happened to another lady and she missed two periods. Just wanted to see if anyone else had similar situation and what happened.
