Very nauseous

Today i got extremely sick from going down a couple of swirly slides w my 4 yr old. In my last two pregnancies that's been how i know I'm pregnant without a hpt. Anything like slides, rides or similar get me extremely nauseous. My breasts feel so much more heavier, sore from time to time. Non stop consistent pelvic stretch like cramps. Can't really eat my favorite foods any more. Any one in the same boat as me??? Really hoping i can give my dh supper exciting news soon
