I'm Sooooo Done Trying 😢

Me and my now fiancee (been engaged for a year now). Are taking BIG steps in our life. Just recently got engaged, about to move into our first apt together, financing our first car together, saving up for a house, me going back into the nursing field to work. Plus he already works in the nursing field but it's just one thing missing... A BABY !!!! It makes me sooo upset when I see people with babies or having babies... Its hurts me more to feel like I can't give him a child of his own (this will be our first child ever). It sucks, when I was soo close once before and it ended in miscarriage 😞 (I miscarried TWICE, other times it just never happened)... It hurt him sooo bad that was the first time I ever seen him cry... He was very supportive and understanding but now I feel like he's slowly giving up on the whole process... He won't have sex when I'm fertile, sometimes I feel like I'm forcing him to have sex on those days when it should never feel like that... I'VE TRIED EVERYTHING !!!! I pray almost everyday for a rainbow baby but it never happens... I take prenatals and vitamin D everyday... I'm 20 about to be 21 on the 14th... Thats all I wanted for a birthday gift this year (to see those two lines)... But as I lay down next to my Mr (we decided to take a nap) I wake up suddenly... I get up cause of course I have to pee, as I go to wipe...

BOOM !!!! I see PLUCKING BLOOD !!! Just great ! 5 days before my period and I'm scared I miscarried AGAIN !!!! Even worse I missed out on another cycle to conceive !!!! By the end of this year it will make 2 years of trying... I know its even harder for some people, I don't mean to sound selfish... I just want to know when will it be my turn??? 😢💔😞
