Blood test/pregnancy verification

Jennifer
Just curious about your 4 week blood tests and if they indicated twins. On my 21 day progesterone test it was a 24 so I was confident I was pregnant. Well turns out I am. So I made my appointment to blood test at doctors office. Progesterone came back 50, which sounded about normal but the hcg was over 1,000. Nurse who told me said that was high and asked if it was my first appointment. It was. So I guess I'm asking if twins is a possibility or if this sounds kinda normal. Please comment your advice! 
Also I got pregnant with femara and an <a href="https://glowing.com/glow-fertility-program">iui</a>.
