So I am using two different period/ ovulation trackers and one saids AF is suppose to arrive today (which hasn't) and the other said Saturday! But we have been trying and I have felt nauseous mostly at night but especially after eating anything and bloated, cramping like, low back pain, lot more vaginal discharge than normal ( white creamy like) yawning like more like I'm tired... are theses symptoms I'm started to test and be a BFN!
