pregnancy issue

I'm just gunna rant to you because I know I can and I don't want to disturb Dennis he's sleeping and what not plus you're my best friend you know more about me then I do. You don't have to respond to this btw

So I don't know why recently but I've really been wanting to get pregnant. I've been getting upset when my period comes and whenever Dennis put a condom on I get all aggravated and upset. What makes everything better is my birthday is the day when I'm most fertile and I'm like well gods trying to tell me something. But I know I'm young and I know I don't have the funds and what not but still I was literally crying for about an hour and a half because I want a baby but Dennis isn't ready/ he wants us to be married and he wants us to be a little more afloat with money (all very valid and I'm not mad at him for that, he's being responsible) but I keep on being nagged about it in my brain. I feel like whenever I see a baby I'm both happy and jealous because of it... I'm only 20 and I'm literally going insane about wanting a baby. And of course my anxiety about everything kicks in and I start thinking Dennis doesn't want a baby with me that's why he doesn't want to right know, I know that's not true but I just get all worried 😩. I dont know why I want a baby so badly I'm so young and I don't have the money for a baby but all I can think about is how I want to wake up and take care of my baby and watch lily grow up and see her smile for the first time and hold her and never want to let her go and have Dennis come home and we both run to him and give hugs and kisses and just play with her and love her.... I want to just come home and see her happy face and smile because she's my baby and I can hold her... I want to make her happy when she's down I want to take care of her.. I get so excited when I think about having a baby I mean I'm literally crying thinking about all of that... I don't know I'm sorry I just needed to rant...
