It's ok. It is horrible to tell people of a loss after they know.
It terms if pain- I had a mc at 9 weeks and I can say that there wasnt much pain at all- just all over aching for one day of the 2 weeks of bleeding
The cramps aches and pains of being pregnant for me is much worse
And I regards to an early mc, what what I have been told at 4 w ish it's not much more than a heavy period
Every pregnancy is different.
You seem to be having a normal pregnancy so far. Keep calm xxx
