Blood test and urine showed hcg hormones [7-9th], barely had a period after my last valid flow which was [sept 1-4 2020] barely came after that little or non, 2 ovarian cyst noticed in ultrasound no g-sac, when exactly did i conceive?

Pregnancy date ?: Since ovulation will occur prior to a period, with the information provided, it is not possible to determine the time of conception. With no gestational sac noted on pelvic ultrasound, the positive HCG may also indicate a pregnancy outside the uterus (ectopic). A repeat HCG quantitative test and a followup pelvic ultrasound in 7-10 days may provide answers.
