I know this may gross us all out, but was wondering if you lovely ladies have suffered bad gastro and diahorrehea during the second trimester?

I am 14 1/2 weeks, and have had terrible gastro pains (like wind moving around in m bowels for most of the last 4 weeks. Most days i get agonising gas pains, and today am suffering diahorrea. im literally running to the toilet every ten minutes.

Is it all normal, or could it just be a bug??

Little worried as these gas pains are that bad sometimes, i literally have to hold my breath and breath through them to stop myself crying in pain.
