Not definite, i have had some pain around the rib from about 13 weeks on and off but over the last week or so it has got worse, sometimes in unbearable. I went to the doctors and they have referred me for a ultrasound so am waiting for appointment. I just wondered what it actually feels like? Xx ive read up on it n symptoms are similar. Sometimes its so unbearable, im not sure if its just position of baby though x
