Rainbow baby days before IVF!

After a month off from treatment,  I took a double dose of provera and was told my period would probably start  2-5 days after stopping the pills, but that it could take up to two weeks. Then I was going to starting my first round of IVF. Already got all my injections and everything! It's been ten days and my period hasn't started yet.. I had no symptoms and didn't even know if i ovulated since I wasn't taking medication.  I just took this test so that I could actually see it was negative and get the thoughts of "but what if a miracle happened on my month off" out of my mind so I could focus on starting IVF.  And then this strong little line came up RIGHT away!!! I am over the moon and so shocked. We only had sex two times this month and I never got a positive ovulation test so I assumed the medicine wasn't going to still be in my system. No idea when I would have ovulated! I did have some brown spotting and back pain a week ago and assumed AF was on her way.. now I think that may  have been implantation. Hopeful this will be my rainbow baby!!! I go tomorrow for bloods! FREAKING OUT! Last year I had a chemical and my second line NEVER got as dark as this test did right away.. hoping that's a good sign!!! 😍😍😍😍😍😍😍😍😍😍😍😍
