I have a 4 month old and I am currently 5 weeks pregnant?

and I feel SO GUILTY...like my daughter will resent me or something when the new baby is born. We DID plan this baby but I thought it would take much longer because it took a while to get pregnant with my daughter and before I successfully got pregnant I had 2 repeat chemical pregnancies so I did not expect this the first month we tried. I knew it was an option so I am not going to act as if I thought for sure it would not happen, and I am happy my kids will have a sibling so close in age... can someone who has kids 12-14 months apart re assure me that your older child did not resent you or feel horrible when the new baby was born?
