I'm confused, can someone help?

Ok, so we are TTC (1st month trying, 2nd month off the pill) but I don't really understand when to test... I know there are a thousand boards and posts out there but I can't seem to find one that answers my exact question:

-If you ovulate around 2 weeks after AF, if you get prego you'll miss you period 2 weeks later, correct? Then you will have a positive test and be considered 4 weeks along? Is that correct?

Thanks for the help!!

That's pretty much the big picture but there are a lot of variables.  You would test when your next AF was late.  Are you planning on temping and checking CF?

First off not everyone ovulates exactly 2 weeks after AF.....for example I'm on day 26 now and still haven't ovulated.  Second you're not making spaghetti so lay off the Prego word, it's Pregnant.

The only way to know when you ovulate is to take your basal body temperature.  Read the newbie link at the top of the page.

So assuming that ovulate exactly two weeks after the first day of your period (which isn't likely) then also assuming you have a 14 day luteal phase (the time between your ovulation day and the first day of your next period) then yes you are correct. But every woman is different and your scenario is based only on averages, not on what actually happens. 

Take my cycle this month for example, I ovulated 16 days after the first day of my period (not two weeks) and my luteal phase averages about 10 days (not two weeks). So its different for everybody.

I don't really know what "temping" and "checking CF" means? I'm new to this.. can you explain?

And also there is a glossary of terms that this board uses on the bottom left of the page. That should help.

Temping refers to taking your basal body temperature every morning, its the only way to know when you are ovulating.

Checking CF or CM means checking your cervical fluid, you body produces different types of fluid depending on where you are in your cycle. Its a way of determining when you are most fertile.

Might I recommend the book Taking Charge of Your Fertility.  It will teach you everything you should know about how your body works and how to get avoid or achieve a pregnancy. It corrects all of the misconceptions that those lovely films we watched in the 6th grade gave us about 14th day = ovulation.

In a prefect normal world, that is correct. A lot of us have found out through charting though, that we have longer/shorter cycles than 28 days and ovulate earlier/later than cycle day 14. For example, last cycle I had a 28 day cycle, but ovulated on day 18, not 14. So, had I concieved I most likely would not have had a positive HPT until cycle day 32 (putting me 14 days past ovulation). Hopefully that makes some sense! Many of the ladies here chart and check cervical mucus in order to track our cycles (when your period begins, through ovulation, and the time after ovulation called the luteal phase until your period comes starting the next cycle). I highly recommend it while TTC!

I actually wondered this myself. If you, lets say, get a positive HPT 14DPO you're considered 4 weeks pregnant? Even though you didn't even ovulate until 2 weeks ago?

Yes I do feel stupid asking this.

Many doctors date your pregnancy by the start of your last period. So if you have a perfectly "normal" cycle of 28 days and O on CD 14, then if you get a + on day 28, then you would be 4 weeks along. However, at your first u/s (and every u/s from there on out) your due date may change based on the size of the babe. Temping and using fertility friend, you can typically find how far along you are by counting back 2 weeks before ovulation. So if you O on CD21, then get a +hpt on day 35, then you're still only 4 weeks along but according to online calculators and many OB's office, you'd be 5 weeks along. And at your first (or maybe 2nd) u/s they'd adjust that 5 weeks back a weekish.

You're essentially 2 w pregnant before you even get pregnant for dating purposes.  This is one of the reasons it's so helpful to chart and know exactly when you (general) ovulated because if you had a very late ovulation on the cycle you conceived, the doctor could give you an earlier due date from your LMP and start talking induction when you could actually be a week from your real due date.
