So i had a period and on my last day i finished in the morning, i then had unprotected sex in the evening. About three days after i had another period which was very strange and it was abit lighter than normal and lasted about four days then a week and a half later ive got pink watery discharge that only happened for a day. I am quite gassy an constantly feel like i need the loo but i dont? If you can help please comment thankyou xxxxxxx
