I think I ovulated 3-4 days ago breasts were very tender 2 days after ovulation and now being 4 days afer ovulation I am very very tired weak feeling breasts are killing me and I am feeling a bit hungry and I normally am not hungry till about a week before my period is to start. Anybody have any input?

Anytime you have unprotected sex there is a 20% chance that pregnancy will occur.

Having said that, we need more information.

Also, once your period is late you could take a pregnancy test, that will tell you whether you are.

Thank you for responding... I had unprotected sex on early early hours of Saturday the day I was ovulating by Monday morning my boobs were hurting. Trying to conceive!

Give it time. If you are pregnant it's definitely to early for any symptoms.

Wait until you are late and then take a home pregnancy test or go to the doctor for a blood test.

Good Luck.
