Ectopic symptoms versus cysts

Patient: My gestational age is 5 weeks and 1 day. I had an iui on May 7th. My first HCG was 48 and two days later it was 143. I had an HCG 6 days later and it was at 1320 with progesterone and estradiol rising really well. Last week I was having extremely sharp pains on my left and right side as well as cramping. Is this something to be worried about? my doctors office said it was probably an ovarian cyst but didn’t know how to differentiate that from a feeling of having an ectopic pregnancy. The pain this week has subsided for the most part but I might get a twinge here and there. I have no other symptoms except constant urination and yesterday I had a major headache all night. I just want to make sure I am not reading too much into what I am feeling or that I’m not confusing my symptoms either.
