Just want to vent!!

We have been trying for abit and after a blighted ovum in November last year and a miscarriage in March of this year

Starting to think my time is running out

Last 2 cycles have been 21 days and this cycle I'm spotting and a little crampy which I never ever had cramping before with my periods

Just want our rainbow baby and first for my partner, I would love another baby as my babies are now 12 and 14 from a miscarriage toxic marriage

Anyone 43 and successfully fell pregnant?
