26 wks & light bleeding.

Leanne
Hi I'm 26 weeks tomorrow and I've had backache for last 2 days. This morning I've had some mild cramping and pink bleeding with little red clotty bits that's now gone brownish in colour. I called medicom an they told me to drink fizzy an eat breakfast and to lay on left side to get baby moving and monitor her movements for 2 hours then call back. This is my 4th pregnancy and never had a problem with last 3 pregnancies. Baby hasn't moved as of yet and it's been an hour. I'm panicking and was wondering if anyone has experienced anything like this and all turned out OK?
Thanks.
