Fertile Week

Ok ladies I need some input. For those of you who are ttc; during your fetile week do you ever get sick, to the point you throw up? For the past year or so maybe longer, I get extremely nauseous and throw up at least 2 days in a row every cycle. It happens in the morning, usually by late afternoon I feel fine. After I've ovulated the nausea is gone until next cycle. Thoughts? Any help is appreciated. Thanks for reading!
