So. TCC. Symptoms or no?

Polly • Im 24years old. My husband is 27. TTC #1 married on 09/14/13. 11months of TTC.
I have a question me and my SO has been TTC now for the last 8 months. I'm worried that this is yet another month well we have failed. In the last 30 mins I have had some sharp cramps. Do those happen when you get pregnant or no? I really hope this month is the month but I'm losing hope. 😣
