Cramping

Brittany

Was supposed to get AF 3 days ago. Last night and today had some mild cramping, almost like period cramps. There is also pressure when I push on my lower abdomen. I do get those occasionally when I start my period, but usually my period comes within a couple hours after that. These started yesterday morning and still no period. Today I have more of an achy stomach. Any ideas? Is this an early sign of pregnancy? Been TTC for 3 months, hoping it happens soon! Any comment are appreciated as this is my first time!
