Hello girls! A question: 36 weeks + 4 days — I've been nauseous since last night, slight pulling in the lower abdomen but not constant, insomnia. Nothing helps the nausea, no vomiting. Who's had this? Is this already a sign that it's time to go to the maternity hospital soon? Husband is at work, I'm alone and scared to stay at home ?
