I wanna get pregnant again...

So I wanna get pregnant again, but I broke up with my bf because he was in jail and he is on parole and isn't allowed around minors so I didn't see the point in staying in a relationship where he can't be around my son. I just graduated college and am job hunting. I have no drive to be in a relationship, but I want more kids. Anyone else feel like this? And no, he is not my son's father. That's a long story that isn't fully related to this. I'm going to make this anonymous because I don't need to get harassed for who my ex is. (He was on the news when he got arrested🙄🤦‍♀️.) Can someone please tell me I'm not alone in wanting more kids, but is single? I probably could get pregnant again... but one guy I know would want to be in a relationship with me and like I said I just don't want a relationship right now. Plus I'm not really attracted to him and I'm not about to use him for a kid. But at least he wouldn't abandon his kid like my son's POS dad did. Sorry I know this is long and kind of all over. I had to get this off my chest. Thanks!

Also, is there any way to heighten chances of having twins? My mom says that twins are in our genetics, but it skipped her when she was supposed to have them, and so she says it's my job, but my brother has 4 kids, no twins and my son is an only child at the moment. 🤷‍♀️ 👶🤰👩‍👧‍👧👩‍👧‍👦👩‍👧 I miss being pregnant and miss my baby being a newborn. He is a year old now, but I want him to be a newborn again. Haha!! I love watching him grow, but I want a newborn again. Anyway, sorry for the randomness of this. Please don't give me too much crap. I just wanted to vent and see if I'm not alone in this or if I am.
