Periods are usually on the 1st of every month and last 5 or 6 days back in July I had my period on the first as normal and then I started my period again on the 23rd but it was only about 4 days and not as heavy found out I was pregnant about a month or so ago and had an ultra sound done on October 16th that said I was 12 weeks and 1 day so my question is when did I get pregnant

Dating is all Best Guess, but based on ultra sound 12 weeks previously.
If Paternity is in doubt then a DNA test is the only surefire method.

So if I am 12 weeks and 3 days now then that means looking at a calendar I got pregnant on July 23rd would I be wrong with my math

If I am 12 weeks and 3 days pregnant does this mean when I look at a calendar my conception date would be July 23rd, 12 weeks and 3 days ago I had an ultra sound to tell me exactly how far alon and I just wanted to know when I concived I know it can never be exact
