Ladies I’m so emotional right now and feel like I can’t talk to anyone my partner or my mates I feel they don’t understand

We’ve been trying for a baby since October 2016 yes I can off my injection then and I know it can take time wel fast foward to February 2018 my first period after 5 years I was absolutely over the moon knowing now is my chance to finally become a mammy!! I know it’s only been 4 months but since we’ve kinda been trying since October 16 I feel so disheartened everytime my period comes I want a baby so bad, my best mate is currently 21 weeks pregnant and my other best mate has just found out she’s pregnant too I am so happy for them and show it but deep down inside it’s absolutely killing me when will it be my time!! I’m so emotional I’m literally crying everyday at the little things and they all talking how happy they are and going out baby shopping I’m literally breaking inside my partner just keeps saying our time will come but will it ever!! I want my baby!! I’m sorry for this long useless message but it’s tearing me upside inside that I don’t have my baby yet!! 😢😢
