since about 11am i have had constant period like pains (not contractions cos they are consitant with no time in between) and my abdomen has been getting hard and tense and i have a small back ache

i also lost my mucous plug yesterday, but had no blood in it!

i rang the hospital and the midwife said to just take panadol and rest, and i have and it hasnt helped at all.

she said to only call back if the pain gets worse , it hasnt gotten worse it just hasnt stopped.

does any one know
What i should do?
