So hard to understand what's going on

Brytnie • TTC BABY #1
For the last week my body has been cramping almost like period cramps. Haven't had a period since January 20th. Been on metformin 2000mg for three weeks Fertilaid almost two weeks and prenatals the same. Yet no signs of AF im not expecting to get pregnant my first month trying but I'm hoping that all these cramps I'm feeling are signs I am going to get AF soon so I know that these meds are working so I can track better to better my chances of conceiving
