I am 25 weeks pregnant and have had lower abdominal pressure and tightness periodically for a month now. It does not feel like stretched ligaments. I do have two uterii and my baby is in the right uterus. Due to having uterine didelphys, I am at risk of cervical incompetence as well. I also tend to have burning eyes and feel flushed as the day progresses. My first baby was born at 28 weeks due to pre-eclampsia. So, as you can see, alot of risk factors here. I guess I just want to know if this pressure and tightness that happens several times through out the day are contractions and if I should worry. My dr checks my cervix via ultrasound every two weeks to make sure that it is not shortening. So, I do not think it is premature labor. Any feedback would be helpful. Thanks.
