am i pregnant?

so i got my period last month although it was really light and i’ve missed my period this month. i’ve taken pregnancy tests which have been negative but i’ve heard some women don’t have enough hcg for months. right now it feels like my uterus is stretching and for the past week every single night i’ve dreamt that i’ve been pregnant and the dreams have been so vivid (i never dream but i’ve been dreaming every night) i’ve also had nausea and headaches but apart from that i’ve had nothing. i’m really curious what this could be it’s close to my vagina but feels like something is being stretched it’s achy and dull pain tho.

edit: my cervix is high and soft and i never miss a period
