37 TTC first time

Jess

I’m 37 and TTC for the first time. Have been trying for 5 months now getting so disheartened every time my period shows and so unfair that’s friends around me are having baby’s I feel so sad and at same time I feel jealous of friends as want that to be me. Is this normal to feel like this? Taking conceive plus, trying every other day in fertile window and outside fertile window. Any advise would really appreciate.
