Please, please try to remain calm. Seek help and advice from friends and family, mommies online, a therapist, your ob. Im sorry to hear your husband is cheating. Awful. Try not to stress so much as it affects the baby and can induce pre term labor and health issues for both of you. I can tell you that i am 10 weeks pregnant. I have 3 children and one on the way. I am in counseling, do yoga, daily meditation and taking paxil for depression. It has saved my life. It is safe for the baby. Your Dr will monitor you often with the medication. Also, zoloft is another anti depressant pregnant mommies take during and after pregnancy. Seeing as you have depression now your probably at high risk for post partum depression. I hope you can work through this. And get some help. Keep udated.
