Any one else struggle??

I have been wanting a second baby for awhile now.. and it seems like itll never happen. I'll either miss my period for a whole month then the next month itll come and my Hope's will be shot down...then this past go around I bled for 2 days of very light pink and brown not like a regular period whatsoever.. and of course tested negative. I feel like itll never happen... theres people having 7 kids and all that and all I want is my second baby...
