A member asked:
I found out via blood i am pregnant. it also told me i am 3-4wks it does not add up to my last period. is this method accurate for determining weeks?

No: The lab lists ranges for HCG levels based upon how far along someone is. They do not determine how far along you are. Trust your dates. Have an Ultrasound. We can measure the Crown Rump Length and determine how far along someone is within 3 days.

Not necessarily: I assume you are talking about the HCG level. The most accurate dating is your last menstrual period, but there can sometimes be a delay in ovulation. If there is concern about your dates, an ultrasound about 8-10 weeks can help.

Would a blood pregnancy test be accurate if you waited three week after sex and you are on Depo-Provera provera (medroxyprogesterone) bc you no longer get a period nevr miss a shot?
Last period was Aug 25th! Been 4 weeks and 2 days since last sex encounter. Did a blood hcg test yesterday and came back negative. The level was <1 so it was below 5. Is it accurate enough to rule out pregnancy?
Last period 12/01. Unprotected sex 12/17. On the mini pill + took plan B 18 hours later b/c I freaked! Period was expected around 12/31. No period. Took a blood pregnancy test 01/10 and it was 0.2. When after sex can I consider my test accurate?
