Well I have been ttc for about a year... I think this time I might be lucky! (waiting to test due to so many disappointments) But some things I have been told, are the obvious, quit drinking and smoking, folic acid which you already are taking, start taking a prenatal vitamins now ( no need to wait til youre preggers). Also, some soda is okay, as long as its not high in caffeine...cut back on your coffee if you are into that. You can drink certain amounts of caffeine daily, but limit yourself to one soda if you must. Also, diet sodas are just as bad because of the aspartame. I would just stay away from it, even though I dont know if anything is proven. Stock up on tums and tylenol(its the only painkiller thats okay to take). hmm I will let you know if I think of anything else.
