Credit Score

I paid my car off a year early, which is great and I'm proud of myself, but I checked my credit score the next month and it went down 30(yes 30) points!! Wtf!? Then I paid off all my credit cards since baby is almost here and I have an unpaid maternity leave and it went down 2 more points since I haven't been carrying a card balance 😡😤. So basically I'm penalized for being responsible and trying not to pay interest. SMH. Just a rant here. Wonder if anyone else has had this type of experience?
