Trying to conceive this month, period 8 days early?

August 2016

My period is due on the 18th, today is the 10th.

My fertile window was the 1st-6th [which we did the deed & stuff on those days 3/6 days]

Now on the 10th i have light cramping since this morning and just right now, i noticed brownish/reddish blood on my panty liner.

[It's never happened before]

I'm 32, and have an 11 yr old. Been trying t conceive on and off for the past year.

I.mainly lose hope and become sad when i get my period, and i lose the will to try. It's a very sad feeling.

Seems like everyone around me is getting pregnant and not me. I feel sad and a little jealous too.

I don't know maybe i waited too long for a 2nd child.

I'm scared that I'll hit menopause or dry up and Ill never have a 2nd baby.

I wish this month is the month.

I don't know what to do.
