Lightheaded and dizzy 5 weeks

Mechaela

I am a CNA and this morning at work I was helping a resident. I wasnt doing much but putting their socks and shoes on but I was very lightheaded and super dizzy. I had drank a bunch of water but had nothing to eat because it was only 7 am. I'm about 5 weeks or so but I never had this issue when I was pregnant with my first one. Just curious if anyone else has had this issue and how can I over come it. I have had a problem being dizzy/light headed a lot lately. Tia

*Also, I dont want to sound stupid or anything but I had a high risk pregnancy with my first one for preeclampsia (high blood pressure), just curious if this could be relatable or it is normal.
