How long should you wait to take a pregnancy test to get the most accurate result? I'm currently 3 days late & not a drop of blood in sight. I spotted light pink 2 days before my period was supposed to start, now nothing.

Also, is there anything i should be concerned about with potentially being pregnant at 34? I had one child at 25, i was considered high risk due to rising blood pressure & low iron. I gained 40 pounds while pregnant but i was only 126 when i found out at 2 months along.

I'm easily 15 pounds heavier than that now & older.

Any advice would be appreciated, thanks in advance.
