So frustrated... And sad! :(

So, we have been trying (not as seriously) for a long time... Almost 2 years.  We have been trying more seriously for about 6 months.  I had an early miscarriage earlier this year.  My due date from that pregnancy is/was next week.  I was sure I'd be pregnant again by now.  We have one daughter who is six.  Yesterday, randomly she told us that what she really wants for Christmas this year is a brother.  I was having all the symptoms and really getting excited that it might have worked this time.  My period is due the day after tomorrow. I just went to the bathroom and it looks like, once again, it's not meant to be this month.  I'm a very positive, laid back person, but this is getting hard.  This month will be a hard one, especially when the due date comes... 😢
