I need advice

Tomorrow I will be 28 weeks pregnant with my first boy.

My daughter was 9lbs 6oz when I had her. Her father and I were both big babies as well he was 10lbs 3 oz and I was 9lbs 13oz.

I have so much discomfort, where my ribs are. The hips and the pelvic region I've experienced with my daughter but this is totally new.

My stomach hurts for like 2-3 minutes at a time sometimes and it brings me to tears. I'm just wondering if I could be expecting him to be big like her or bigger...or if I should worry and bring this up at my next doctors appointment Wednesday.

I'm just wondering if I need to worry or if any other mommies have experienced this with their second child. Oh and my kids will be pretty close in age. She was born January 10 and he's due January 23/28th
