Should I be worried

Katarina
The other night I got heart burn so bad I didn't know what to do! (I used to get it really bad before I got pregnent but used to pop a few pain killers ) anyway I manager to get it to ease off and got some sleep... The following night it happened again! (Now linked to cheese it seems) the second night however I was in aggony and must have pulled my neck and back... 
My neck is soooo stiff and sore now and accross my shoulders too.. Has any one experienced this ... I'm a bit worried because I stupidly googled it and all said about ectopic etc ... I'm 5w 5d my first Midwife appointment isn't till 25th feb ..
