Have done 2 tests both with super faint positives. Almost not noticeable but still there. My sister was able to see the first one. AF isn't due for 8 for days but I've been having nipple tenderness, lower back pain, crazy appetite, and a few headaches for the last 2 weeks.... last period began on 7/19 and I spotted for the next week after my period, then the symptoms began. Anyone else experience anything like this?
