I’m 16 weeks with mono/di twin boys and I started noticing the last week that I have been more uncomfortable, is that normal? My hips and back get sore much easier, my feet have started to swell when I get warm or have been standing a while, I get sore and crampy in my lower abdomen, acid reflux every day... I feel like a baby because everyone says the second trimester is supposed to be easy, but I feel like I jumped from nausea to soreness really quick. Also, I am a FTM so I have nothing to compare to.
