Being a great mom and being ready to be one are two different things. Just because your T told you they did not think you were ready to be a mom, does not mean they think you would be a horrible or bad mom. Did you ask your T why they felt that way and what did they say?

We went thru in vitro 3 times. Very expensive and stress full, 3rd time we got twins

During pregnancy you will need to stay off your meds. Some women can do it, some can't. I had a girlfriend many years ago, she too was bipolar. She already had one daughter in foster care that she just got back and she also became pregnant. Not by me,when I met her she was pregnant. She told me her pdoc told her to abort because he did not think she could last full term without meds. She decided to try any ways. At first she was fine and I really thought she could do it. But by the 2nd month off meds she started getting out of control. Serious mood swings, anger issues, and she drank behind my back. Long story short, by her 6 month, even she had to admit it was not working and aborted at her 6th month.

The point is there could be legitimate reasons why your T did not feel you were ready and perhaps you should have talked to them about that more. I will try to be supportive of you no matter what you decide to do. Some people can go without meds better/longer then others. I've gone 5 years! Everyone is differently and there are always a lot of circumstances involved. Just look at the big picture. Patience! Best of luck to you!
