im 36 weeks and am generally not an energetic person but know i will need to excercise after baby is born, a couple of days this week i have taken very short and slow paced walks however last night i got cramps very low down like contractions. ( this is dc2) could i have caused this? and am i risking early labour if i keep on walking? they really are the slowest of walks because as i said i am unfit and a very short distance. the only reason im doing them is to try and get myself used to being active before baby is born.
