Finally pregnant....but

Finally pregnant...happiest woman ever.

But since pregnancy I've been having crazy cramps! Has anyone else experienced this?

Also been told that I have to inject clexane twice a day due to my weight...for the entire pregnancy great.

I haven't been taking it coz I have a phobia and I'm one of those people who shun medication and all these government produced things into my body so I'm really second guessing (don't leave your nasty comments about this)!

Anyone else taking clexane? Any studies showing its usefulness?
