However, on the 25 I've been feeling nauseous at random occasions mainly in the morning.On the 26 I've been feeling light cramps with some slight bloating and tenderness around the nipples.Today on the 27 the cramps have increased and I feel as though my period is coming. Yet when I check there I a small amount of clear/chunky white discharge.Would this be considered implementing or not.
