Feeling Frustrated

So I've been doing really well since going off Lexapro for my anxiety. I haven't had any problems except for a couple of days before I start my period. I noticed this happened last month and again this month. I talked to Kim about it the other day and she suggested talking to my doctor about  switching birth control pills. I thought this seemed like a good, logical idea. I went to my doctor today for a physical for work and I wasn't very happy with what she had to say. Her suggestion was to not switch my birth control because it might mess up my cycle, give me cramps, and cause trouble with acne. She thought it would be a good idea to prescribe me Prozac to take just during the week before my period. I was NOT happy to hear this. I thought that she would be totally on board with switching my birth control. It seemed like the next logical step. Prozac seems drastic. I asked a lot of questions. I had a hard time when I first started Lexapro waiting for it to build up in my system. It made me feel weird and I don't want to feel that way again. I guess there is a possibility it could, but if that's the case then I don't have to take it. She wrote me a prescription for 20mg for 30 days. She wants me to try it during my next cycle and see if it helps. I called Brian, my mom, my friends, and Kim to get their opinion. Mixed reviews, but most say I should give it a try. I know that if I don't like it and it doesn't help I can look into switching birth control or something else. I just really don't want to be on anything, you know? And honestly these past 2 times I've had anxiety before my period sucked major bad while they were happening, but I got over it. I'm feeling great now. Aside from the stuffy nose and sore throat that I have recently acquired. I'm just feeling really frustrated with the whole situation. I guess the best thing I can do now is not think about it or worry about it until next month and only if I need it.
