Paxil during first trimester

I'm 30 yrs old and have been on 20 mg paxil for 2 years. I have been doing great on this med after multiple times of trying other meds with no improvement of anxiety and depression symptoms. Almost 2 weeks ago, I came off the paxil because my husband and I both want another child. I stopped my birth control at the same time. I went thru about a week of horrible physical side effects of withdrawal such as dizziness, nausea, headaches and so on. Now, just past my ovulation time, I'm having severe depression issues, irritability, and anxiety that is making my life as well as that of my husband and son, a complete disaster. I'm beginning to really believe I need to be on my meds because I can't function now. I know the paxil is a class d pregnancy drug and now I'm completely lost as to what to do. I have fertility problems as it is and all I can see is my chances of another child slipping down the drain. I want to talk to my dr to see what to do but I can't see her until the end of next week. Any advice? I think I need to go take it now but there is a very small possibility I could have conceived already but its too soon to take a pregnancy test.

Thank you so much for your response. My husband is usually very supportive but not so much during this fiasco. But I don't know if that's just the way I'm feeling because of bein unmedicated. But my mood is swinging back and forth pretty bad. I have less patience with my child and when I have over reacted, I immediately feel extremely guilty and apologize. It's not his fault I'm a mess right now and that's what makes me think I need to go back on my meds. I've been trying different coping measures and techniques to try to balance my moods out, but none have worked very well so far. Usually lots of sunlight and exercise helps but wouldn't you know it has rained daily for the entire last 2 weeks. I may just need to move to the coast.
