Postural Hypotension ?!? First Trimester

Have any of you ladies experienced this? It happens when I stand up from a sitting or lying position. I get a sudden head rush and feel lightheaded almost like I'm going to faint. I have to bend over for a few seconds and wait for it to go away and then I am fine. I noticed this about a week after finding out that I was pregnant. I am almost 10 weeks and just wanted to know if anyone else is going through this. When I google it, it does say it could be from the pregnancy from hormonal changes or a couple other different things. I do have it every day mostly the first half of the day and then the evening and night I don't have it anymore. I do not remember having this with my daughter and it is quite scary.
