Fifth doctors visit

My weight was 134 my B/P was 96/63. I asked my doctor if my blood pressure is ok since every time I go in it drops more and more. He told me that my blood pressure is still probably going to drop because my body is producing more blood and the blood vessels are getting bigger. OK as long as it is good. On the sonogram he showed me all four chambers of the baby's heart, the stomach, and bladder. He baby is getting so big. Also all the bones are darker than last time. He was not able to give me a picture this time because the machine ran out of paper. I have been feeling good this month not as tired. I also have been feeling the baby move just about everyday. Next appt. is late September.
