Trying to stay positive

My husband and I have been TTC for some time now. My last period was a week late. We had started to get excited as AF is pretty regular. I mean sure, I've been a couple of days late here and there throughout the years but she's never, ever, ever been a week late. Every other cycle since we began TTC, she arrived on time. Having her arrive after a week was crushing.

My husband is 34 and I am 30. I feel the pressure of the clock. Sometimes I feel like I am being punished for being responsible and waiting until I was a) ready for children and b) in a stable, supportive and loving relationship with a man who wants children. It took me ages to find my husband and involved a cross-Atlantic move (I moved to the UK to pursue my MA and Ph.D) and as a result, I'm coming out of my peak fertile years. But what was I supposed to do? Have a kid with a guy who was barely boyfriend material and definitely not father material just to have a child?

I am trying to stay positive but it is so hard. Every day I feel like someone else is announcing their pregnancy. It stings the most when someone who wasn't trying or hasn't been trying as long...I want to be happy for them but it hurts so much.
