Idk how to feel 😞 confused

My first day of my last

Menstrual was 12/4/2022. Yesterday I found out I am 5weeks n 1 day pregnant. Me and my boyfriend were so excited but last night I was slightly cramping in my lower abdomen mainly discomfort on my left side. So I decided to go to the ER it felt a lil off to me, so when i got there they drew my blood and urine sample and an ultrasound. So when I got my paperwork it said

No IUP. Endometrium is diffusely echogenic and measures 1.9cm in thickness. Also that it can still represent an early pregnancy due to my LMP dates. That therefore with serial beta-HCG levels is recommended for further assessment to exclude ectopic pregnancy although one is not seen. Idk what that means!!!? 😞 Also I have left ovarian cysts, one hemorrhagic and one simple. Small amount of free fluid in the cul-de-sac. As anyone experienced all this before or is going thru this as well? 😕
