Braxton hicks and leaks?

So I was sitting down drinking some hot chocolate with my fiancé at the coffee shop and then I felt stuff come out and it felt like a lot but it wasnt. But my Braxton hicks are probably happening every 20-25 minutes and it's in my lower back, it feels like those period pains almost. All day today. I get them in my belly for a few seconds too sometimes. Im 33 weeks and 2 days. Do they become more constant and more as I get further along? I'm a ftm. Is it something I should bother my doctor about? Yesterday she was kicking my cervix like crazy, and she was in some nerve and made my right leg go numb constantly, also I had the back pain and tummy pain basically all day. I worked 11-7 no breaks or lunch yesterday all day, and I'm a chashier. Don't know if that info helps at all.
