I’m 36w3d and my dr said it was fine to take and the instructions on it. I haven’t done vaginally yet bc I’m kinda scared haha but I take it 3x a day orally. Everytime I take it I get extreme BH but they are longer then usually and painful so I guess turning into contractions. Not my first child so I know. Anyways they stay for about 3 hours and then go away. Has this happened to anyone else? Oh yes and baby is extremely active when I get these contractions.
