I was just wondering if it's normal for me to have cramping at this point of my pregnancy. I am 16 weeks and since this morning I have been having period like cramps that start on my sides and go to the lower middle. It is getting annoying. It's not painful, just feel like period cramps. I have also noticed that my feet swell by the end of the day. My shoes are fitting me tight already. Is this normal? By the way, I'm having triplets so I don't know if that's what's causing this. Please, any advice would be great.
