TTC 7 months.

We have been trying to conceive for 7 months now & every month I get just as excited as the last waiting to see if the two little lines appear. I’m 25, soon to be married and my partner has a six year old. It’s suppose to be my “ovulation day” tomorrow, today I just feel like another period is coming - it’s not due. I’m hormonal, emotional and just generally feel tired and grumpy. Is this normal? I took a home ovulation test yesterday after another app says my highest ovulation day was yesterday and it had the faintest second line. Starting to get disheartened. Does anyone have any advice?
