last week i went to the hospital due to bleeding it was caused by a uti so they said bleeding was normal so then yesterday i went in again because i started having heavy bleeding and a small blood clot they told me everything was normal but i was reading that my hcg levels are low but it can be caused by early pregnancy. has this happen to anyone ? and it also said i have no free fluid i don't go to my doctors till tomorrow and i'm nervous 😭😩
