Melanie
Yesterday, whilst out shopping, i got a sudden headache. So i went straight home and had a nap, when i woke up i was fine again. Then at 2am the following morning i woke up to a horrid headache again & feeling nauseas! I had a bottle of water and went back to bed. Again, ive woken up at 7:30am and feel fine. 
But thennnn... i went to the loo, and when wiping noticed a large amount of my mucous plug, with slight bloody tinges through it. 
Now, i am having the odd 'tightening' feeling in my lower abdomen, and have also had 2 sharp shooting pains. 
I hope this is the start! 
Anyone else experienced similar?
