movements at 18 weeks. how strong are they? I think I feel him moving I get little bubbly feelings ever now and again. it's been four years since I was last pregnant I don't remember. I'm worried since I'm high risk. I want to the er last month due to spotting and cramp but he was fine strong heartbeat. at my last appointment on the 4th he had a strong heartbeat don't go back til the 2nd of next month.
