HELP :)

Hi guys! Im on CD 15 of a normal 26/27 day cycle. The past couple days, ive been having some nausea in the mornings (usually subsides by early afternoon). Probably WAYYYY too early to be having symptoms (maybe i have an ulcer or something). Something weird keeps happening. It feels like an eye twitch on my right side. It seems lower than my normal ovary pain. Any ideas? :)
