I had been out walking a lot today and when I got home I sat on the sofa for a good 15 mins before getting up again. Once I got up I was hit with this kind of ripping sensation in my lower abdomen. I had to sit on the floor until it eased and standing up made it worse. It went away eventually and didn't come back. I'm 16 weeks and 3 days and I'm just a bag of nerves about this pregnancy, very paranoid and now I'm worried about this being something major. I've had no bleeding as I checked. I have my 16 week check tomorrow so will talk to midwife about it and see what she said but can anyone ease my mind before then? Could it of been ligaments?
