Ovulation help....

Emma • Finally pregnant after 5 months! 😍

So according to Glow my highest fertile days are today and tomorrow but my OPK this morning at 930am was negative as were yesterday's (I tested twice yesterday) however I feel terrible today, waves of nausea, emotional and headaches which i have read can be a sign of ovulation .....what the hell is going on??

Today is also my birthday and I defo don't feel like celebrating 😢
