Crinone -when to stop?

Patient: I have been on Crinone due to bleeding in early pregnancy, and it worked wonders.The doctor never checked my progesterone levels, they just put me on it and said to get off them after 9 weeks.At 9 weeks I got another bleeding and a different doctor told me to stay on them for 12 full weeks. I am now 13 +2, but SO scarred to stop taking it!!Should I get my levels checked before?Is there any risk of me taking them for longer?Kind regards,Malin
