I'm 18wks now and my body hurts bad this is my fourth pregnancy but this time my lower back really hurts me bad I'm not sure if it's growing pains or what,? It comes and goes on & off every few seconds and I don't know what it could be I feel fine other than when the pain comes & goes and bothers me. If anyone else has experienced this pls feel free to share on what you may think is causing this. I'm open to all suggestions😥
