Am I pregnant or am I not?

Alyssia

I’m 4 months late my first day of my last period was May 16th I have been having spotting on and off I took a test it was negative but two weeks or so ago I’ve been nauseated and so tired my Brest are fuller and heavier. I don’t know what to do I have issues with pee stick tests. I haven’t had to bad of cramping it’s more of mussel pulls and very dull pain my lower back hurts a lot. I noticed that it’s a very light to brownish color and that typically a sign of important or pregnancy. I need help from other people because my first pregnancy was different from if this was to be another (pregnancy). What are y’all’s opinion on this, please help?!!!
