Cant believe my eyes 😱

I’ve been diagnosed with pcos for a year now and the doctor put me on metformin I think which helped me ovulate. We’ve been trying to get pregnant since July 2016 with no luck . We decided it’s time to check everything’s ok and had numerous amounts of tests done last week . Before visiting the doctor I had all the symptoms of pregnancy though so I asked her for a blood test for pregnancy confirmation which came back negative 😒. I gave up and was waiting for AF to show it’s ugly face. When I started to believe m no longer pregnant all my symptoms vanished mysteriously. I now have severe cramps and nausea. I was supposed to get my af on 28 which neva came. I dint test for the fear of getting a negative . DH has been pushing me so I finally took a home test today and violaaa..!! I can’t believe my eyes ..is this true ?? Is it really happening?? Why did the blood test come out negative ? Wasn’t that supposed to give more accurate results ? Anyone with similar experiences

Hoping for a sticky bean🙏🏻 Baby dust to u all ladies

Btw we’ve been using pre seed from the past two months.
