It s been a week since I had protected sex with condom. And it s my first time to have sex after 3 years of abstaining. After 3 days, I felt weird feeling in my stomach, frequent belching/burping, lost appetite, and loss bowel movement. Last month I started my menstruation on January 15th. This month I have menstruation yesterday (February 17th), and I m still on my 2nd day. I noticed my blood is just light, and today I saw very tiny or little black spots in my pad. What does this symptoms mean? Please enlighten me. Thank you!
