Braxton hick help

I'm a ftm and have had Braxton hicks only twice so far. I'm 33 weeks 3 days. Today I woke up feeling period like cramps in my lower abdomen. The first time I've had Braxton hicks it just felt like I had to poop but baby was moving as normal. Today I've only had a little movement but not the normal. The Braxton hicks don't have a pattern so I don't think I'm in labor. My main question is when should I call the doctor? I mostly worried since I haven't felt baby move a lot. He is a very active baby throughout the day. Any advice will help.
