Light spotting

Hello I’m currently 38 weeks 5 days pregnant yesterday morning i got up and went for a walk came back home and 2 hours later i went to the bathroom to pee and notice that a had real light spotting on the tissue ...when i went back to the bathroom again to use it i notice that the spotting had gone so yesterday evening around 7 ish i was on my way home and a cramp hit me as i was driving ...made it home and i experienced another cramp getting out the car (don’t know if they were Braxton Hicks or not cuz they felt completely like period cramps lol didn’t hurt at all) but anyways i was cramping on and off for like 3 hrs however i don’t think they were contractions because they were way to far apart maybe like 30-40 mins but anyways cramping had stop and i went to sleep got up around 11:45 almost close to midnight to use the bathroom and notice the light spotting had started again the spotting eventually stopped but this morning when i got up to use bathroom it started right back ...does anybody know if this is normal ? Should i go to er and get check please help me out i already tried calling doctor office but no answer. So let me know what you guys think. Thanks
