I have finished my period and today is the 16th day from 1st day of period and i started feeling sts:########s such a - No ability for food and even feeling like vomiting after eating - Feeling i need to sleep alot and my body is tired. - Some hardness on my lower stomach where uterus stands. I asked people they said i cannot feel any symptoms of pregnanct before a month. I want to ask is it possible to show pregnancy on day 16 from the period? or is it just psychological thinkings?
