I need mommy’s opinions

OK I will be 37 this year and I just gave birth to my third baby my children are 4yr 2 yr and three months Old I just got the copper IUD and it fell out and I just got back from my OB and sign the paperwork to get a tubal ligation but I’m not quite sure that’s what I want a big part of me does not want to have no more kids and then there’s a part of me that wants just one more maybe in two years if there’s any women on here who has had a tubal ligation and regret it please help me change my mind I don’t want to make the wrong decision and then later on want my fourth baby and be unable to have it not gonna lie sometimes I’d rather not be a stay at home mom but for the last For years that’s all I have been my kids are difficult because they’re so close in age but I know it’s time it’ll get better just not quite sure I want to be pregnant in my 40s I’m just so confused about all of this I guess I just need some mamas to give me some encouragement and help me figure out what I truly want thank you for your time
