Me and my boyfriend cuddled with naked upper bodies but we were wearing our bottom wear that means four layers of clothes I was wearing my legging and panties and he was wearing shorts and underwear. I saw a small drop. Of semen on his shorts but he did not ejaculated it was just a drop. After this incident I am felling restless from a few days and even my body get warm suddenly at night for 2-3 days. Is it a symptom of pregnancy? Or its just PMS. please reply we are really worried.
