Since the day I found out I was pregnant I have suffered with cramp in my thighs. Not painful just really uncomfortable. However in the middle of last night I woke up screaming and crying with the most horrendous painful cramp I've ever experienced. Was screaming so loud I woke oh up and he was shouting at me 'what's wrong? What's up? Is the baby ok?' And I was in so much pain I couldn't tell him what was wrong. When I finally could speak I told him it was cramp in my leg and he let out a huge sigh and burst into tears. He thought something was wrong with the baby bless him I actually had to hug him to sleep to calm him down because he was in such as state. But even today it's still painful but not as bad as last night. Is there anything I can do to prevent cramp?
