Thanks for your comments.Oooh.I had my period today.
I meant to say you will have a period within 16 days of ovulation. SORRRY!
In pregnancy, your breasts can change almost immediately after conception. Also, in pregnancy your symptoms fluctuate (meaning sore one week, not sore the next). Or your cycles could be changing.
Your ovulation is not based on your period. Your period is based on your ovulation. Meaning that you will have a period within 16 days of your period. You don't always ovulate on cycle day 14 (or two weeks after your period). So if you ovulated late, your period could be late.
It could possibly be that your experiencing PMT symptons but try another pregnancy test in a few days to make sure!!! Good Luck!
