Cycle day 31; TMI (no picture)

Alexandria
I have a normal 28 day cycle, and I'm on cycle day 31 without any with of AF
​I had some light spotting about 2 weeks ago and a speck of pink spotting last week. 
​Tender breasts under armpits, tired, hungry, headaches for the last three days, mild nausea, back pain, emotional like I've been crying about everything, acne is coming up and I had some light fluttering in my lower abdomen today, but I keep getting BFN. :( 
​I had a BFP a day before my missed period with my chemical last month so I'm not sure what's going on.
