I am 4.5 weeks pregnant with my 2nd child.  My expected period was due this past Sunday, and received a positive test on Saturday. Everything has been going well until today. Three different times today after using the bathroom I have had SLIGHTLY brownish discharge. I mean it is FAINT (my husband had to look hard to see what I was talking about) but it is there. It's not even showing on my white underwear, but is there when I wipe. I have also had mild cramping. 

 I contacted my doctor who said it should be fine, but to come in if it increases. However, I couldn't help but Google it and now I am having a bit of a meltdown and am of course thinking worst case scenario. 

Has anyone else experienced this??
