Could my pregnancy symptoms be suggestive or real?

The last time I had with my partner was on May 27th. It was his 1st time but not mine. Everything was fine until he brought up the questions, " I'm not gonna be a daddy, am I?". I mean why would he bring that up if he doesn't want a child and neither do I?? So anyway, ever since then I've had the doubt also and it's driving me nuts. I've taken 3 HPTs all of them at least a month apart to avoid the "it's too early" false answer and they've all came back negative. I can't go by a missed period sign because I only get mine once or twice a year so that doesn't help my dilemma. Around July during I noticed a little droplet of a clear fluid from my left and I freaked out of course. I've also gained a little wait but I know this can be due to stress which I'm sure under right now. Could I still be pregnant even with the negative HPTs or is this all suggestive? :|
