QUESTION

Dear Midwife,
Hi, I am 25 years old and I just found out on Jan 8th that I am pregnant. The thing about it is that they could not find the baby.

Three years ago I lost another child through miscarriage and I am scared about the light pink color when I wipe myself. Granted it is not there everytime but I am still worried and slight pain on my right side.

I also am a diabetic and I take 100mg of metformin twice a day. As of right now I have stopped because I have no idea if it will harm the baby.

I won't be able to pick a Dr. for another two weeks so can you please try to ease my troubled mind?

ANSWER

Please do not stop taking your medication without telling your doctor. Metformin is safe for pregnancy; uncontrolled diabetes is not. If you are concerned about miscarriage and it is too soon to see the baby on ultrasound, then they can do blood tests to verify that the baby seems to be developing ok. The tests are called "serial hCGs," and you might also request that they check your progesterone, since you miscarried before. Good luck!
