I know it was working yesterday, but I'm not sure if it's still in my system or not. I took it around 12pm yesterday, it is 8.6mg of sennosides (if that helps). It's just a generic vegetable laxative. I know it says you should produce a bowel movement in 6 to 12 hours and I did, so is it still working through my system? Anybody know how long it takes to go through completely? Thanks in advance.

I'm asking because I am 38 wks pregnant and 1 cm dialated and trying to distiniguish between laxative cramps and contractions. They feel VERY similar! Thanks again.
