<s>[INST] hello mam in my last cycle egg was not ruptured till 22nd day .its size was increased till 37 mm.in this cycle the size of eggs was not increased on 18th day it was 15.2but on 21 day they got smaller.pls tell me what should i do. [/INST] Hi, welcome to Chat Doctor. Forum. Did you have the scaling on 22nd day of last cycle, 18th day this month, and on 21st day of the period? If that is the case also your doubt might be correct. But egg can't be visualized in scaling also, as it is a single cell, and you need an electronic microscope topee it. anyhow don't worry. If it is for conceiving consult a gynecologist, and have a baby. Thank you. </s>
