BV and Cramps

Catrina • 25. Married to my other half. 5-15-15. 1 angel baby named River. Daughter named Remington. Son named Journey.
Been using the gel to get rid of the bacterial vaginitis and today I had some cramping that was worse than the normal cramps. No blood or anything but it was strong. Anybody else experience this while using the gel? 
Or should I go to the ER and make sure everything is okay?
