I'm courious to know how the pregnancy wheel works. I got my period the beginning of December 2012. Had sex with an ex of mine in December 2012 a few times the last I remember was on December 24, 2012. I got my last period on Decemeber 30th- January 2nd. I ended up going to a party juanary 5th 2013 got wasted and had sex with a friend of mine. It wasn't till February 5th I took a pregnancy test to find out I was pregnant. I went to the doctors and they counted 2 weeks back from the first day of my last period which was Decemer 30th 2012 but that just really confused me and I'm really neevous about who the father might be. Is there any way you can explain to me or tell me when I might have gotten pregnant exactly?

Like this one?

If your last period was 12/30/12, you most likely conceived on or around 1/13/13.

With that said, this is all just a scientific calculation based on averages. Not every woman has a 28 day cycle and this wheel is based on just that.

Whenever 2 partners are involved a DNA test will be required to determine paternity.
