I have been running for about a year now, usually 6 or 7k, 3 or 4 times a week. I have just discovered I am 6 weeks pregnant with dc3 and am debating whether or not it is safe to continue. The main reason I am anxious is due to the fact that I bled throughout most of the first trimester with dcs 1 & 2 (had not taken up running at this point either). A friend has mentioned stopping for the first trimester, walking instead, then resuming my running in the second trimester. Any advice?
