Month 8 ttc

So month 8 ttc #2,#1 conceived in one month she's 2 in July. Also had a mc last January which took 3 months to conceive. Af arrived last week bang on time,I was so relaxed last cycle compared to other months/cycles. We bd in my fertile time,tried opks and temping. I know when I ovulate.if I'm honest when we first started ttc I didn't think it would take long due to it happening quickly and easily before,but suppose every times different.im still young. Not sure what where doing wrong. Is this ever going to happen?!???!? I know some people have been trying A lot longer,but I'm just worried it's never going to happen . Just like the rest of you ladies I want this so so bad,it's on my mind everyday without doubt I just feel so useless:( is this ever going to happen???
