20.... ttc... and nothing..?

so i've been trying to conceive with my fiancé... i was on the pill for about 5 years and came off it in roughly nov/ dec last year and we've been TTC since then..

i'm 20, 21 in jan... and i've been with him for a little over 3 years, he's 32 so a little older, we are both so ready for a baby .. and i'm so confused as to why it hasn't happened yet.. none of us have had kids before but i've had two chemicals for the past two cycles... is there something wrong? or is this normal?

please no one say 'you're so young you don't need to be trying so hard yet or getting worried'

i ache when i see others with their children, not just a baby, but that amazing bond and i want it so bad, and i'm so ready.. we both have full time jobs, our own house, our two little fur baby's and both drive, we are so ready..

anyone have any ideas why this is happening to us? or do you think i should get medical advice? i'm so scared ... 😞

thank you everyone i appreciate any advice Xx
