Is it normal during the 2nd trimester (18wks) to have lower abdominal soreness when pressing on the abdomen? It is sometimes sore when I push on it. And it also feels like pressing on my abdomen puts pressure on my rectum, like I need to use the bathroom.
Get used to it. I'm 37 weeks and I am still getting those aches and pains. Its caused from your stomach muscles stretching to accommodate that growing baby inside of you. It feels like you've done a lot of sit ups or crunches, right? Thats what mine felt like at that time, and if you think about it, your stomach is working out just the same. All of that stretching going on is bound to cause some discomfort.
I haven't/didn't feel any pressure on my rectum but on my pelvis. But we are all different! Like I have to go pee all of the time, non stop. The pain is almost unbearable sometimes. It wouldn't hurt to call your doctor or midwife to find out if it's normal. It never hurts to ask!
