Hi
I had some brown spotting with #2 at 5 and 8 weeks.
I was advised this is fairly normal.
As for the blood tests, your doctor will be wanting to monitor your hcg levels to make sure they're rising. A lot of doctors do this.
I was offered it with #1 as I had a history of miscarriage, the same with #2. I opted not to, but it was nice to know my doctor was proactive
Good luck!
