feeling strange, should I go to hospital???

Yesterday I was in the city shopping with my best friend. And as we went into KFC for a bite to eat I started to feel strange, I cannot describe how I felt in words. Just didn't feel right. Almost a kind of anxiety worry feeling, like I was going to faint, then I started to see little black dots floating before my eyes. And they went a little blurry, like that usually with a severe magraine. But no headache. Eventually it went away, but it wasn't too long later as I got a little more tired and fed up walking about, I started to get strong contractions. I'm guessing it was braxton hicks. But a few of them weren't too far apart. Eventually they fully stopped. But I was totally drained of energy. then late last night, I started to feel faint, and funny. (That anxiety feeling again) so I lay down, and went to sleep. Now this morning, same thing, feeling sick, and anxiety, with a little blurred vision, cramps in my tummy, no energy and this shooting pain in my left nipple. I'm now 30 weeks pregnant with my daughter. She's also been very active since all this, and it's making me feel woozy. Should I head to the hospital or is that too drastic?
