Hd myomectomy(4 fibr)and hyst 7 weeks ago, regular period 1week after 2nd period 25 days after that and now suddenly ond cd16 started again, is it norma?

Could be: I presume that the hyst was a hysteroscopy, unless you had a mnyomectomy which turned into a hysterectomy. If you are having this bleeding after a total hysterectomy, including your cervix, you need to see your physician. There may be a problem at the vaginal cuff. If you still have your uterus and fibroids were removed, this could be totally normal, since you are still having cycle.
