Trying not to stress.. light to medium cramping and spotting

m

Ever since I found out I was pregnant I've been constipated. Well it's gotten better but have had to stain. I do have endometriosis so when I have to go I get pretty bad cramping so I wasn't concerned until yesterday in want getting good. I have been able to gave a bm the last couple of days. I started having some cramping not to bad on and off yesterday then last night I had some very light brown spotting when I wiped. Not every time I went to the bathroom and still this morning. I did have a mc in November and this is around the same time I it happened. I'm 6 weeks. This is different from last time. I'm still worried and not sure what to do.
