History of midcycle bleeding growing up around cycle days 8-10. they found a small uterine polyp but it went away after sometime. spotting went away after kids. now today about 1.5 years since my last mid cycle bleed.it happened again.should i get us?

"Mid-cycle bleeding" is often caused by two follicles being released, which along with increased stimulation of eggs (at age "33") results in higher estrogen just prior to ovulation, and the drop in estrogen at ovulation is similar to onset of withdrawal bleeding in menstruation. Ask your GYN physician about oral bcp's, which stop ovarian hormone production and therefore mid-cycle bleeding.
