Early labor?

Okay So today I've been having some stomach cramps down my by pubic bone, I've had several episodes of diahreeah, and when I like squeeze my vagina muscles like I feel a little gush of liquid but it doesn't happen every time. I also had my wife check my cervix and she said it feels different. Like she said normally it feels like pushed out (she motioned with her finger) and now it feels pushed in like before I got pregnant. I went to my OBGYN today and he listened to his heartbeat and he was fine, my blood pressure was a little high and I had some protein in my urine but they didn't seem to worried. I constantly feel like the pressure of having to pee. I'm only 25W1D. I'm just worried cause my nana and mom both went into labor at this time. I was born at 26 weeks and my nana had her twins at 26 weeks also. Does it sound like labor is coming or just general pregnancy weirdness. I also have a ton of neausea... Like I was drinking tea and almost threw up. Also, baby is still kicking a little. I'm worried about him.
