Hi and welcome to HCM!
Thanks for posting your query here.
Follicular studies are done to know about the ovulation and its time. Ovulation means release of ovum from the ovarian follicles. In a 28day menstrual cycle the ovulation happens on 14th to 18th day. This is the most fertile period. If the sperm enters into the female uterus
there are maximum chances of fertilization. Your follicle ruptured means ovulation has happened.
Eugest 200 is a hormonal
preparation which is progesterone
. This hormone helps you in supporting the fertilization and its implantation
in the uterus.
Safely you can use the tablet. After using the tablet for 2 weeks on the first day of your missing period you can check for pregnancy
All the best. Hope this is helpful to you.
