TWW and just found something out..

Samantha
I'm only 3 dpo and I've been TTC number 2, and I just found out that my husbands sister is pregnant. I feel happy for her, and super jealous at the same time. I know it's not right to feel that way, but my sister in law wasn't even trying. She just happened to become pregnant when she missed her birth control and her husband didn't pull out. I wish it was that easy. With my first, I conceived on the first cycle (I was temping and taking OPKs). This time around, we've been trying for 7 months. I feel good about this cycle, but I feel like she'll feel slighted because no one knows we are TTC. Is that weird? I'd like to hope that she would be happy for my husband and I, but sometimes his sisters can be quite petty. I just don't know if what I'm feeling is normal.
