Lower pressure and twinges

Kim
AF is still a week away but suddenly today I got super crampy and felt pressure low down. The cramps weren't like period cramps but more like twinges or pain every now and then. We've been ttc since April and I'm super frustrated so this month I really didn't test or take temps. We just had sex every other day since my period ended. Trying not to get my hopes up but can't help but wonder what those pains were. Anyone else have similar pains and have a good outcome?
