I’m having a little potty party - excuse the rant:

I’ve had two back to back chemicals (one while on birth control) and I have no clue when my cycle is due. If I calculate based on the last time I bled (which was also the last time I had a positive pregnancy test before this one) then today should be the start of my cycle. My lines are faint and don’t seem to be progressing like everyone else’s and I’m afraid of chemical #3. Here’s today’s test... has anyone else gone through this? Could my dates be off?
