Hi Hannan,
I know how you're feeling, it's a really anxious time and it's much easier said than done to relax but do your best to.
If you get any pains/aches that you're worried about, get to the docs.
I had terrible pains and I've been spotting for nearly two weeks, my docs have been brilliant and an early scan has shown that there's a little heartbeat. I'm feeling much more relaxed now.
I can't wait to get past the first trimester.
