Hi I'm after some advice I'm not sure what to do 
Found out I was pregnant beginning of August, had some brown spotting/cramps 19th and 20th August so was given an early scan on 23rd August which put me at 5w5d and on internal scan they saw heartbeat although my dates from LMP put me at 6w2d. Last night the brown spotting/cramps started again but the brown spotting is worse it's every time I wipe and slimy (sorry TMI!)
Iv tried ringing the EPU this morning but no answer I'm not sure if they open weekends and I don't know what to do...iv had one healthy pregnancy (he is now 5) never had this with him I'm petrified I'm having a mc 
Has anyone had this and how bad can the brown stuff get before I need to do something (not sure what that something is!)
