SMH U Guys!

So I’ve had irregular periods for the longest so I decided to change some eating habits and fairly exercise to try to balance my hormones so that I can have a regular period. In January I stopped taking my BC(birth control) and I had a period in February. March I had a period again. April’s here and no sign of my predicted period. I took two pregnancy test and they both say negative. Could I be experiencing irregularities again? I’m so confused and so over it.!!!!!!!!!!!! What should I do?
