Nervous but still hopeful

I have PCOS , was diagnosed 11 years ago. We went through infertility treatments for a year , I got pregnant with twins , shortly after miscarried . It broke my heart and I didn’t wanna try again . Doctors put me on Depo for 10 years to stop my horrid bleeding. I got off of it in October. In March my period came back and for they were normal ! Which the doctor said they wouldn’t be . I also started eating better and losing weight . I’m think I ovulated last month and am now 1 day late for my period . My boobs have been sore and swollen for over 4 days , light nausea and cramping , but doesn’t feel like period cramps . Only other time I ever felt like this was when I was pregnant. I’ve taken 3 tests over the past week... all negative. I’m really hoping my levels just aren’t high enough yet . Gonna test again on Thursday... I really want my rainbow baby
