Still waiting but symptoms help (baby #2)

Ok girls! I’m having heaps of symptoms they came pretty fast. My boobs grew 3 inches this week,noticed that my nipples were way darker last night and I feel like my lactation is picking back up (stopped bf about 4m ago). I had some cramping earlier this week and have this fullness/bloat that won’t go down and I can’t seem to right my core anymore because of it. Not to mention I feel like I need to pee ever 10 minutes. Also I got so lightheaded and dizzy after my workout last night I almost passed out that hasn’t happened since last pregnancy. Am I crazy? According to my calendar I should wait to test till the 20th, don’t want to get my hopes up
