### output:

Hi Nisha, Let me explain the process. You have periods for 4-7 days, during which time the eggs which are to come out of ovaries are getting ready. As they get ready, the inner lining of uterus keeps increasing, so that its thick enough for the baby to fix or implant on time. In a 28 days cycle, the eggs, (inside the follicle) is growing in size & around day 12 of periods follicle ruptures letting out the egg. Egg moves into the Fallopian tube, a bridge between the uterus & ovaries, where it waits for the sperm for 24 hrs(that's the lifetime of egg - 24 hrs!), if you have sex around that time or just before that, Sperm will be waiting in the tube (lifetime of sperm is 3 days/ 72 hrs !) If they meet they form baby, which swims into uterus to get fixed there. Doctor gave those pills to increase the health of eggs & also to increase the number of eggs recruited. You can have sex whenever you want, any number of times, no problem. Best timings are-Daily or alternate days once bleeding of periods stops, so that old/ elderly sperms are thrown out, till day 10 of periods. Day 1 of periods is 1st day of periods. Then no sex for 3 days, so that fresh & young sperms accumulateThen again daily at least once from Day13-17 of periods, which is the time of ovulation. Hope I have clarified your overall the best Chat Doctor.
