Well I been hurting for about 5-6 hours now I don't know if I'm having contractions because this is my first pregnancy but it's like my stomach gets tight and it does that for about 1 minute my doctor said if my whole stomach isn't tight then it's not contractions but it's been going on for a few hours and it's usually across the bottom of my stomach into my back ! Right now it's like permanent it won't go away ! It hurts so bad 😞
