Could this be baby #2?!

So, earlier this year around June, I became pregnant with baby #2. After a few days of finding out, I ended up having an early miscarriage, or so my doctor called a "chemical pregnancy". I wasn't trying to get pregnant, in fact, my son is such a handful, I really didn't want any more kids. Once I had accepted the fact I was pregnant, I was happy... until the doctor told me I was no longer pregnant and it wasn't viable. Even then, I accepted it and still wasn't trying to get pregnant. For some unknown reason today, I took a pregnancy test. Something just told me to take one, and sure enough, it says PREGNANT! I'm definitely not sure how to feel at the moment. I feel happy/sad/guilty/nervous, I for sure made an appointment to confirm the pregnancy and take tests every single day to know for sure that this one sticks!
