I am 10 weeks pregnant tomorrow. For the past couple of days I’ve had mild period like cramping radiating to my groin. Since becoming pregnant I have had a lot of cervical mucus, today the cramping has died down but I have noticed a slight brown tint to it which I have not had before, no increase in the amount of CM. I have had 2 scans this pregnancy one on 30/12 and one yesterday, both have been great. Yesterday’s showed that the baby had doubled in size and had a strong heartbeat (like it did 2 weeks ago) should I be concerned?
