Wanting to be pregnant so bad🥺

So I know I’ve only been “actively” trying for 3 months this will be my 4th month, but I seriously am starting to get upset about it although I’m always positive.. no matter how much sex I have, no matter how I catch ovulation it just is not happening like why?? It seems like literally everyone is getting pregnant around me I sometimes have the urge to be jealous & I’m like why the fuck are you pregnant and I’m not, or some people that didn’t even want to be pregnant😒but then I just come back to my senses & im like it’ll happen, then it doesn’t. I’m trying my final solution with pre seed this month and if it doesn’t work I feel like I’m just gonna give up and say fuck it even tho I want to be pregnant so bad I wanna have a baby so bad. Sorry for the long paragraph I guess I needed venting.
