I’ll be 35 weeks tomorrow. Noticed some back pain last night before bed and during the night was up every hour to per. At around 5 I woke up with period like cramps and back pain. Nothing too painful- just mild pains. Didn’t come and go as such, just sort of eased off after 15-20 minutes. I’ve just been noticing back pain this morning again. Baby moving loads. Is this normal enough or any cause for concern? Just keen to hear what others thoughts are!
