My tubes wewe tied August of last year. I've never had any irregular periods until last month. I had one period at beginning g if month and a very odd one at the end cause it was late. Then I was 3 and a half weeks for it and now it's very brown spotting. I've had a lot of cramping on left side of belly button and lower back pain along with sleepiness and extreme dizziness. Should I be worried? I have no insurance
