I need help

Hi so here’s what’s going on. June 6th, I started spotting intermittently. I actually thought it was implantation bleeding because I’ve never spotted a day in my life before. I kept spotting for 16 days and then nothing. So I was like ??? Wtf just happened??

I took a bunch of tests and ruled out that I was pregnant. So fast forward to this month. It’s the 18th and I’m having pregnancy symptoms (vivid dreams, heart burn, fatigue, acne, more CM, very sensitive nipples) but I don’t know when I could possibly take a pregnancy test. I’ve taken some for here and there, one yesterday, and one two days before that, and one this morning because I didn’t do FMU yesterday and all are negative (I have bad line eyes). So wtf is going on? When do you think I should test?
