Effects of first time sex

Ok. So I lost my virginity 2 weeks ago but 2 days ago I started leaking this odd discharge. It won’t stop. It happens every couple of minutes so I have to go to the bathroom to change my pad. Does anyone know if this is from sex? I’m really starting to worry because I don’t want this to last forever 😓 I went to the doctors today and even he said he doesn’t know why it’s happening so I’m starting to freak out
