Is this Normal?

Im 26 years old ... I found out a few weeks ago that I was pregnant ... Initially, both my boyfriend of 6 years and I were super stressed out about it as the timing was not the best, but after maybe two days of sweating it we both grew very excited.... I lost my baby three days ago at almost 6 weeks ..... Im shocked at how quickly I grew sooo attached to my little bean as I have not cried this much since I lost my father 6 years ago 💔 .... But here's the thing .... Although I was nowhere near ready for a baby or even thinking about having one, for some reason I now want one more than ever ... My boyfriend is hurt about the miscarriage as well but now that its happened he isnt interested in trying again .... Ive been feeling turned off by him because i feel like he's being selfish because he already has a 10 month old baby (yes he cheated and I took him back and  accepted his child) and I feel like he expects me to hold off on my life now because he already has 1 child to deal with which i dont think is fair ... Eitherway... The question here is, is it normal to want a baby so badly now that I've lost one, even though it wasnt even on my mind at all before??
