Not pregnant

Hello so ive been cramping since yesterday (8dpo) and today (9dpo) i am still cramping like my period is going to start. I took a pregnancy test and got a BFN. So sad bc i have changed my unhealthy eating habits, drink more water, took pink stork fertility pills but they were turning my urine neon yellow so I stopped. Someone recommended me to take fertility smoothie. Im going to try it! Has anyone had a success story using fertility smoothie. By the way I am still not on my period yet but major cramps and negative test since yesterday.
