Not keen for sex like at all!!

Okay can anyone relate ! I’m just off 13 weeks pregnant 🤰🏼 and I also have a 7 month old who I run after all day as well as clean and cook and everything else a mum does! And I work once a week & my baby comes with me to that!! I just sooooo can’t be bothered having sex and not even horny a little bit ! My husband is pretty helpful around the house but I just don’t feel like having sex & especially not foreplay! I know his craving it was two weeks since so we sort of just fucked I said I wasn’t feeling foreplay at all! Anyone relating to this ?!
