Is it common to have increased contractions after an internal exam? I am not spotting or anything, just having worse contractions and lower back pain. I was 2 cm's this am at the docs office, but I am only 34 weeks so I need to be watching out for preterm labor symptoms. I think I am just be a hypochondriac, but they are definitely more painful. I think I probably need to start timing them, the only problem is I feel the contractions as lower back pain and not sure how you time those.
