Low blood pressure!!

Kristine • After 6 years ttc, we are finally pregnant. I have an 8 year old son and have been married for almost 10 years.
So my blood pressure at 11+4 was 110/67. Nurse was concerned a bit but not much. I have been getting headaches lately but they aren't horrible. Anyone else have this. What does it mean? Btw...here's my little bean, and we heard the heart beat and my hubby cried!! It was beautiful!!!
