Hello I am also 29 and this is my first pregnancy. I the same type of cramping and its totally normal. had my first appointment today and I'm due January 3. Hope you feel better soon
You'll definitely feel light cramping as if your period is coming which is normal. It's just your uterus getting bigger and prepping for a human to grow. If it's intense cramping and bleeding then definitely contact your doctor.
It could be round ligament pain. Everything is stretching. It's completely normal.
However, if it's accompanied by spotting, bleeding, headaches, or lightheadedness you should consult your doctor.
