Is there such thing as a reverse due date calculator?

Is there such thing as a reverse due date calculator?

Sort of: If your due date is based off of an ultrasound, you could then see when you most likely had your menses and when you conceived.

Is that what you mean?

If you are sure of your menstrual period, it should correlate closely with your due date from an ultrasound.

I hope that helps. :). ...Read more

Edd based on 14w u/s.Reverse due date calculator says I concieved may 19 is it poss. I could have concieved may 30. Couldn't date by lmp (depo?

Doubtful: An US done at 14 weeks should be accurate within 7 days. So it is very doubtful that conception occurred 11 days off of that May 19th likely date of conception. Seven days either way, but very doubtful that it's 11 days off. ...Read more

How accurate are due date reverse ovulation calculators?

Varies: Depends how accurate your due date estimates are. If you have a super-reliable dating then the reverse calculation is "pretty good, " like within 3-4 days. If your EDD is +/- 2 weeks as it often is, then the reverse calculation will be not useful. Good wishes. ...Read more

Are conception date calculators accurate if your 7 weeks and 8weeks ultra sounds due date are the same. I'm due April 26th 2015?

Are conception date calculators accurate if your 7 weeks and 8weeks ultra sounds due date are the same. I'm due April 26th 2015?

Yes, but...: An 8-week ultrasound scan gives an accurate estimate of the dates. All dates are estimates, so even an "accurate" estimate is an estimate. If general, there is no need to look for an exact date of conception, because life is never exact, and women are having sex with only one husband or future-father-of-the-baby at a time. So, the date estimate from the ultrasound scan is accurate enough. ...Read more

If your ob tells you your edd is 03/12/14 according to your u/s. Can a conception calculator be used to find out an estimate conception date?

Not accurate: We frequently get this question when there is more than one possible contender to be the father. Sorry, it doesn't work that way because there is a margin of error in the u/s and there is no guarantee that you conceived exactly at day 14 which is what those calculators will assume. Best of luck. ...Read more

My EDD Is 12/7. My last "period" was March 2. Last time I had sex was 2/26. According to conception calculators I conceived mid March? Why is this off?

Incorrect dates?: Is the EDD you are going by based on your last menstrual period? I noticed you put period in quotes so are you unsure of this or was it not a normal menses?

I use the ovulating calendar and calculator and my menstrual Calendar and they all say 11/5-11/10 and my ovulating date is 11/8 is it correct?

An approximation: That date is only an approximation. Actual ovulation could happen any time during your fertile window. If you want to be more precise, you should buy an ovulation predictor kit at the drug-store. You can check each morning of your fertile window to see if you are likely to ovulate in the next 12-24 hours. Ideally, if you want conception, you should have intercourse BEFORE you ovulate. ...Read more

I had unprotected sex november 16, 2013 everytime I put that into a online pregnancy calculator under "date of conception" its says im 4 weeks. Why?

Easier calculation: Every pregnancy dating software is based on a 40 week pregnancy. Actually the pregnancy is not 40 weeks but 38 weeks. Not every women knows when they conceive but women know when their last menses occurs. Therefore the dating is from the last menses artificially adding 2 weeks to every pregnancy. ...Read more
