Shall I call NHS 24?

Ali
I have had 2 previous miscarriages. I had a scan on Thursday and everything was ok apart from I thought I was further along than i was (5 weeks). On Thursday before the scan I was spotting brown discharge. I told the midwife and she didn't seem concerned about the spotting. It then went away after a couple of hours. Friday no spotting but uncomfortable cramps. This morning and today I've had more brown spotting when I wipe and menstrual like cramps. Shall I call NHS 24 to be on the safe side? I can't stop worrying.
