Hi, just after advice and or your thoughts. I'm due at the end of this week. Have had back pain all day in my lower back and in my rigjt bum cheek/thigh. now have like a stitch stroke pulled muscle feeling in my lower belly. Not really coming and going in any noticeable way but also not entirely constant. Pretty sure I lost mucus plug last week and baby was 3/5ths palpable. Is this it?
