Everyong getting pregnant but me

I feel like everyone around me is having babies and multiple of children too! Me and OH been trying for a while now and nothing but negative results! I haven’t had my period in 127 days now! Last period was September! Always miss my periods during winter and i don’t know why! Getting upsetting now as I just want to be a mum so bad. We have a lovely room made up and two beautiful cats waiting for a baby to be guardians of! If we don’t have any luck. My OH gets a money coming from his family so said we will go to a private clinic to help get pregnant! Was really hoping this morning I will get a positive i don’t know why when... no periods no ovulation, no ovulation, no baby! Im so done seeing people younger then me having loads of babies! I wish i got pregnant before 25 because i was a but more regular then! 😭😭😭😭
