Early pregnancy signs! Let's share!

So I have tested since 9DPO with today as day 11. The line is getting darker so I am hopeful. Reading a lot of posts on here makes me even more hopeful. Still really early though. Anyway, this is my first and at the age of 36, I know what my body sounds like, how it feels, how it moves, twitches... And now I have no clue what it's doing. If my BFP holds true, these are all pregnancy symptoms. I like it but it's weird. Among the few symptoms, random headaches and dizziness. But I've had on and off cramping in my lower abdomen. Very different from period cramps. Is this my uterus expanding? Anyone else feel this at 4wks? I'm excited but scared. Would love to share stories! Baby dust to all!!!
