question

My husband and I have been trying for 3 months now and still nothing. I'm curious if this is normal? I had the mirena in for three yrs. now I only get my period like 2 days. He has a son already and I miscarried a few years ago. I'd love to tell him I am but now every time I get my period I cry. Is this normal. My doctor says stop stressing it will happen. Then she says hurry up I'm 35 in feb. I mean we're trying. I just sad I guess. We really want to be pregnant and everyone keeps asking I say no but now it's bothering me.. any advise thanks
