How to calculate weeks?

Hi mommys Did some research online and they say to calculate weeks based on last menstrual period date. But for sure I know I ovulated late this month (probably after cycle day 24)…. Last menstrual period is 10 December Conception date first week of Jan Only tested positive after missing period for 6 days My period cycle is usually about 30-35 days. Not exact.. How do I know how many weeks I’m in? Thanks in advance

hi! i myself not sure how to calculate hw many weeks im in 😅 based on our LMP, theres usually a calculator online to help give a rough estimation of how many weeks we are. from my personal exp, so far the estimation has always been about the same as to when i went for my first gynae checkup. https://www.whattoexpect.com/due-date-calculator/

Still use LMP to calculate number of weeks. Anyways that one is not accurate. Based on gynae first scan is more accurate.
