Cramps and spotting


So my fiancé and I just started trying this month and this past week I’ve been cramping all day and night nonstop we took 3 test all came back positive. But the dr won’t see me until June 29 they are guessing I’m only 2-2 1/2 weeks along but the cramping won’t stop the there is very little brown discharge starting to show up. Is that any reason to be concerned.
