I heard that you can identify if you are ovulating by the smell, it's like a sweet smell.
If this is true, in my situation my period was supposed to come on the 7th, It's the 10th already no period and my area have a sweet smell, since a week before de 7th that I can remember.
I know it's too early for a pregnancy test. Is there a possibility that I am pregnant?

No, you cannot diagnose pregnancy by smell alone. This is a myth. If you have not had your period you need to take a pregnancy test using first morning urine.

I have never heard of that before.

And it's not too early to take a pregnancy test... if you are late take one.

That's right I took one 2 days late and had a positvie so take a test
