Spotting

Cookie
I am 6weeks 4 days for baby #5. I've had 1 miscarriage in the past and 1 blighted ovum. I'm a bit worried because I have been spotting brownish color discharge for the past 3-4 days. I feel some Left side discomfort but I think it's constipation related.  OB won't see me until the 22nd, so I'm in the waiting game.
Anyone else have spotting in their first trimester? Please pray that all will be okay with baby. Thanks!
