OK I had my cycle in January and February but not march then it came in April but I feel these little flutters in my stomach and my back is hurting but that's it could I be pregnant?

It's April now. You just had your period. Why do you think you are pregnant?

Anyway, it's much too soon to feel flutters. It's probably gas.

Miss your May period, wait two more weeks after that, then do a home test with first morning urine.
