help please

Me and my boyfriend are sexually active, he lives a couple of hours away, so when we meet usually we are horny. I saw him this weekend and he stayed at my house, we always use condoms, we didn’t once a while ago. Today my discharge out of nowhere appeared to be a reaallyyy light green, it doesn’t smell, i don’t have any other symptoms, such as itchiness, just a weird discharge. Right now Im not financially stable so i cant go to a gynecologist. help!
