Hey there lady, im 12 weeks today and at 9 weeks (by RE that was filling in for mine who was on vaca) i was told to stop taking it, i didnt, after what has gone one, hes nuts. well i met my new ob monday and she said she usually has her patients stay till 13 weeks (im going to wait till the end of 13 weeks basically 14 weeks) by then the placenta should have taken over for sure!! Good Luck and Congrats your almost into 2nd trimester!!
I stopped right about 11 weeks. Congrats on the pregnancy
I took till I was 14 weeks although my ob forgot to tell me when to stop so I just asked him at my 14 wk appointment and that's when he told me to stop.
I was on progesterone through 13 weeks.
I was told to stop taking it at 15 weeks, which I did. My doctor said it was fine to stop at 12 weeks, but that since I am a worryer it didnt hurt me to take it up until 15 weeks, kind of overkill but he said that would ensure my placenta had completly taken over.
Congratulations on your pregnancy!!!
