My symptoms seemed to clear up while I was cramping, too, but then came back. Yours might hit harder in a day or two!
I've really been battling with nausea, sore/tender breasts and nips, and a really sensitive sniffer. They're all symptoms that came on early with my past pregnancies, but I don't have the terrible headache this time, which is hopefully a GOOD sign since my headache always intensified right up until the losses. Also a bit of a runny and bleedy nose, but that could just be the weather (sooo cold and dry).
