### output:

Hello Landing;welcome to Chat Doctor You have not ovulated in this cycle that is probably the reason that you have got your menses. As there was maturity of your follicle, but there was no rupture of follicle to release ovum, so there was no chance for conception. Naturogest is micronized progesterone preparation which is give for Luteal phase defect, and it should not be the reason for early menses. Thanks
