Confused and want to cry

I'm 17 dpo. I took a test at 14 dpo and it was negative. My breasts have been sore and swollen since 5 dpo. I ovulated on October 18th according to glow. I have a 28 to 30 day cycle. My period is 3 days late. I have crazy nausea, my boobs are super veiny and sore, total loss of appetite, period-like cramps, brown mucous spotting only when I wipe and vivid dreams. I'm nervous to test again. I don't know if I should wait it out or get to my doctor, because I have had multiple losses before 8 weeks and I know there's nothing that can be done to prevent it. I'm frustrated and just needed to rant. Google is the devil. 🤦🏾‍♀️🥺😩
