Ok, i found out im 4 weeks pregnant. I went to the er, n confirmed. They did an ultrasound where the said my uterus tilted, its alot of free fluid, my endometrium is thick, but no fetal pole . They came to me n said my hcg 64.5, nn thay its low, and its possible itsits no sign if a baby or it may be to early. Can u explain all this? Is it too early? Should i worry
