Im 4 months pregnant and I’ve started getting really bad headaches and eye pain and any light makes it worse, i wake up from this pain in the middle of the night and cant fall asleep. It goes away for a fee days when I take 2 asprin but it comes back. I’ve started seeing things, like something small black it looks like it runs across the table and im thinking its a spider but its nothing, i see that several times a day anywhere. Other things begin to look strange too. Like moving.
