Pretty sure I fucked up

My husband and I have a 9 week old. Now I’ve become extremely moody to the point where everyone around me sees it except for myself. I got a little tipsy the day of our anniversary and we had sex and he wanted me to get him off by giving him head.... ok, then he like pulled me back on him! I am so scared I am pregnant again.🤦🏽‍♀️🤦🏽‍♀️🤦🏽‍♀️
