Help !!!!

I got 4 positive test at 3 at 10dpo and 1 at 11dpo lines are getting darker also went to my obgyn and got a faint positive so they did do bloodwork! I’m having very light cramping it comes and goes. I’m supposed to start tomorrow usually I’ll have bad bad cramping to where I’d have to take medication for the pain, but it’s very light and comes and goes. Should I be worried?
