Hi! Yeah, with this pregnancy (I'm 17 1/2 weeks), I had baby-brain BAD. Luckily I got pregnant fast, because I'm sure I could not have standed the wait. This is my third child. With my first child, we also got pregnant very quickly. Both times, I was taking birth control, stopped, and was immediately pregnant. With my second daughter, it took me 18 months to get pregnant with her, and I hadn't been taking birth control. For me, it was the BC that regulated my cycle, and allowed us to get pregnant more easily.
Either way, you know that it *can* take a long time to get pregnant, so I hope you're trying to think of ways to keep your mind busy so you aren't making yourself crazy! I know it's so hard!
Good luck, hope it happens very soon!
