Lately i have noticed that im having more discharge and peeing a lot more.. (could very well be normal)

Just now i went to the toilet and i just finished peeing and i felt something drop.. i wiped and there was a big chunk of green mucus about the size of a 20 cent peice..

I don't know if this is at all related but i have been alot more uncomfortable lately, iv been having terrible BH especially at night time. My back just wont stop aching..

I know that pre labour symptoms and everything can last for weeks so im not freaking out but is it something i should be calling up about or should i wait and see if theres more mucus?

TIA
