Second child too soon?

Au

In general how soon is too soon? I got my bfp tonight at 10:07. Wasn’t expecting it and we were trying. Currently have an almost 13month old boy and I’m not thrilled but not mad. I am however upset with myself because a child is a blessing no matter the timing. So I feel guilty for that and the fact that my baby didn’t get to be a baby long enough. Any advice or words of wisdom? You can chew my ass out too if you think it’s selfish of me for feeling this way. I just need some people to talk to. I don’t think my husband is exactly thrilled with the idea of another child considering he only wanted one after all our heartache.
