Have been having back ache and sharp ish twinges in ovaries the past couple of days, woke up today with very runny nose and flu symptoms, also lots of creamy white discharge. Took a test this <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and was BFN, could it still be too early or would you say I'm out? Anyone with similar CD tell what your current symptoms are?
