I’m pregnant with #2

My baby girl will be one in December. Today I woke up feeling so sick. I’ve been waiting on my period to arrive. Ever since I had my baby my periods have been about 35 days apart. I still had like 3 more days to expect it. But like I said I felt sick this morning. Felt like I was about to puke.So I went to the store and got a test. Got home and took it and 3 minutes later, 2 lines appeared. I’m speechless. I have no words. I even felt butterflies in my stomach...? I remember feeling those with my daughter but I was further along when I felt those? Why am I feeling that right now? My last period was October 12th... I don’t know how to feel about this. I wanted to wait till my daughter was 2. I know no one will understand this but I just feel like we’ve been terrible parents with our first. My husband and I had no idea what we were doing. I just feel guilty. Should I talk to someone about this? Should I be feeling this way? 😭
