Good afternoon everyone! I'm 28 weeks and 3 days. For the second day now, when the baby moves and when I walk I get a pulling sensation in my lower abdomen. It's like contractions but not long and it passes quickly. Is this because of pressure on the uterus? Also, insomnia has started. I barely manage to fall asleep until morning. Painful legs syndrome. My right leg and arm — everything hurts. Aching pains, it really throbs. I'm taking calcium but it's still the same. Has anyone else dealt with stomatitis? Like a white coating. Candidal stomatitis?
