Think I'm having a chemical

Rachel
The top test is yesterday morning and bottom is from this morning.  According to glow I'm 4w2d.  Got a HCG test yesterday and it was 32 and progesterone was 11. My doctors office seem to think these were ok.  Have to go tomorrow to see if it doubled but by the looks of my tests I doubt I'm going to get the news I want. Also had some brownish discharge a couple of times when I wiped today and pretty bad back pain.  I feel like I have no one to really talk to about any of this. If I lose this baby it will be my 4th miscarriage since October 2015.
