So if i am ovulating an i had sex since friday and from sunday i hve lower back pain can that be a symptom of pregnancy?

Ovulating When?: You can get pregnant for about 24 hours when you are ovulating. I often have m y female patients worry about the five days prior to ovulation just to be sure. But, once ovulation has occurred an egg must be impregnated and then travel to the uterus and then implant. It is unlikely to have any true pregnancy symptoms till implantation has occurred. So no, not on the day you ovulate.
