I'm struggling a little bit today. My cousin and his wife just announced that they are pregnant with baby #3. She just got her birth control out a few months ago...and looking at the timing, they got pregnant right away. I'm super happy for them but I feel like I was punched in the gut at the same time. I've always struggled with irregular cycles and I don't always ovulate on my own. We tried for a year before getting pregnant with my daughter then almost 2 years with my son (with the help of clomid). We decided that we weren't going to try for another but we aren't preventing either. So these feelings that I'm having are confusing. I'm feeling jealous that it comes so easy for them, while I'm over here struggling with infertility. I just want to cry...why can't my body be normal???
