So confused!

Shannon

I have no clue what my body is doing!!!.. I believe I had a chemical pregnancy last month and now according to my tracking app I am 15DPO and 2 days late for my period. I keep testing and I have been getting vvvfl for the past few days.. but being first response tests they could very likely be indents!.. been having light cramping on and off for 5 days now, every so often when I wipe I get a bit of brown discharge..

Anyone else conceive after a chemical?.. what were your symptoms / signs?.
