Hi, I'm pregnant for the first time, and with twins. Since finding out I was pregnant I've felt what I can only describe as dull period pain in my lower abdomen which I mentioned to my midwife and she said that was normal. However since the early hours this morning I keep getting short sharp shots of pain especially on the right side of my my bump, plus more frequent period style cramps across the whole lower abdomen. I'm not due to see the midwife again for another 2weeks. Is this sort of cramp/pain normal?
