Almost 4 weeks, super anxious

Hi everyone! I'm 33 (almost 34) and got my bfp last Friday at 10dpo. First it was a faint line, but on Saturday even the digitals picked it up. Today was supposed to be AF day, and I've had light cramping since Sunday night and today some spotting. I took another test and got a very strong first response test (line as defined as test line) my first appointment isn't until April 7, should I be worried? I spoke with the nurse yesterday and she said cramps and spotting is normal. Am i being a paranoid first-timer? Thanks all!
