Headache gone mad!

So I have been taking test all neg and I had blood test today won't find results out til Friday. I have had all kinds of symptoms from sick to stomach, really sore boobs and nipples, lower back pain, I am also 15 days late. But the worst symptom is that I have severe headaches and I get one everyday. Has anyone had symptoms like me and ended up with a positive test?? I'm adding this anonymously be I don't want my family to know. Until I know for sure
