Mmmm I had them but can't remember the reason why, I do know mine were related to being really tired all the time. Try drinking lots and lots of water to keep hydrated while your body is building your little bubba. Neck massages might help too and getting lots of rest. I took panadol when they were really bad - I'm a teacher and if they were awful and the kids were loud well the 2 didn't go too well together and I figured me taking panadol was the lesser of 2 evils. ( I could see the newsheadlines - "Pregnant teacher loses the plot with ratty kids" ) Good luck and I hope they ease up soon hun.
