Im 34w and i take two 500mg capsules everyday and one vaginally everynight RIGHT BEFORE BED. you just poke a hole in it and stick it as far up in your vagina as you can before you go to sleep and wear a panty liner bc it leaks a little.
Another mom on the site used it and it helped her... She went into labor, i think a week or two after she used it. She told me how to take it.
It doesn't necessarily start labor. It softens your cervix.
If your 35-36 weeks I suggest evening primrose oil. I have been taking three a day since I was 36 weeks now going on 38 & went from 50% effaced to 100% & 2cm dilated it helps thin you out and helps so you don't tear while delivering!
Also drink a glass or two of raspberry herb tea!
