Hey.. I'm a 17 year old girl and I'm having some MAJOR problems. So I'm in a sexual relationship and we barely use protection.. I started getting tummy ache and so did a clearblue preg test twice in 4 weeks but not pregnant. I'm also secreting this very runny, watery discharge after sex, before sex and pretty much throughout the day. Feels like period but it's not? What could this be.. Please help me.
