Maybe Mommy This Month?!

Sooo I BD only on cd 11 before SO had to go out of town but also on CD3 during my period. Today I am CD13, and I know it is crazy early but I have been nauseous since yesterday. Had anyone had nausea during ovulation? Yesterday I had ovulation pain on my left side and smack in the middle and just felt sluggish. Today has been hard to shake the nausea. Do you think it is promising we only had sex once during fertile window and had ovulation pains the next day?!
