Possibly pregnant?

Brandie • Momma of a sweet princess and 2 sweet boys
My husband and I have been ttc for 7 months now after back to back loses, I've been testing for a few days now and all have been negative, today I took a dollar store test it showed negative, but hours later I got a positive line. Has anyone else had this happen and actually been pregnant? exact thing happened with my second pregnancy but don't want to get my hopes up
