what to do??

not sure where to post this but would like some opinions... I have 3 kids from previous relationship (2 boys 1 girl), my man & I now have 2 boys together (so I have 5 kids). we just bought a house, everything with us is great. I am 5wks postpartum & at my check up I decided to go with getting my tubes tied bc that's why my parents think I should do since I suck at remembering the pill & don't want anything inserted in me & my body didn't react well to the depo. thing is, I'm oddly scared of getting my tubes tied. I've read a lot about it & all the cons scare me enough to not want to & I'd rather just avoid sex completely lol even though that's going to be impossible. anyways, my SO has hinted to wanting to try for one last baby because he would really like a girl at some point & as much as I would like a girl too i just don't know if I would want to. not because of the pregnancy part, but because of all of the judgement from my family. I just hate hearing what they think. my oldest is 8, I have a 5yr old, 4yr old, 16 month old & 5wk old. I wouldn't want to try again for at least 3 years & by then I'll be 28 & maybe I'll change my mind by then plus it seems like boys are more "dominant" here so my chances for another girl would seem unlikely anyways... sorry for the rambling kind of just typing as I'm thinking lol. (no government help, my parents don't have the kids all of the time just sometimes when they want them so it's not like they're taking care of them) we just bought a new house so we have the room & all of that... what would you ladies think?? need reasonable thoughts
