Without having sex on almost 5months.Im experiencing vaginal brown discharge lately (first time) , i am taking 28days pills (trust) im on my 14th day , i missed the 14th-17th pill . yesterday i bought 28dayspills (trust) and take the 14-17th pill , after that i feel somethingy on my underwear. I thought it was just a white mens , but im shocked because its kinda brown. Why is it so??
