quick bout of nausea 8 dpo?

hi ladies!! so I'm 8 dpo and I think I just had a quick bout of nausea.  the sick-to-my-stomach feeling came quickly but left quickly too, like maybe 15 seconds? am I imagining this? I had cramping 4-6 dpo and some pinching pain on my right side today. CM is creamy/lotiony and still very much present, much more than usual and never lasts this long after O. thanks for any thoughts!! xoxo
