Help! Missed period, Sore breasts, high temp!

You probably ovulated later than usual or had an anovulatory cycle. In both cases you will just have to wait until AF comes. Most commonly, women start their first cycle day 14 days after ovulation. Imagine you ovulated on the 31st of December, that would mean your next cycle would start around the 14th of January.
If you had an anovulatory cycle, your body will shed the lining of your uterus by itself after a while, but there is no way of knowing when.

If you are not sure, you can always ask for medical advice, progesterone can give you all sorts of symptoms without being pregnant. Otherwise take another test!x

 

Just like I explained in my previous post, you probably ovulated later or not at all. It happens to a lot of women. I once had a 55 day cycle instead of a 28 one, just because I ovulated 2 weeks after I was supposed to get my period.
If you think there is something wrong, either test again or go see a GP.x
