Do i just need to relax???

Im currently 15 weeks 4 days with my fifth pregnancy. I have one child who is almost 8, and have gone through three miscarriages. Two of which were this year. Anyway, i have been cramping really bad for the past 3 days. No bleeding, but i have had some very snot like discharge. The babys heartbeat is normal, i check about 4 times a day with our home doppler. Should i just calm down? Is it just normal pregnancy pains? My OB cant see me before monday, but i do have the option to go see my high risk specialist that i see regularly at anytime i need him, only he is over an hour a way. Should i make the trip? Or am i just panicking myself?
