33 weeks today and I was really restless last night and at about 530 this morning my stomach started hurting really really bad and I had a ton of pressure down low felt like I needed to use the bathroom couldn't but it hurt so bad I felt like I was going to pass out and then at about 9 I couldn't stop using the bathroom it went on and off all day until about 2 pm... I read online that it could be a sigh that labor is close is that true?
