Provera

So after not having a period since January, then spotting for 6 days super light brown I forsure thought it was implantation bleeding Now I’m 2 and half weeks in of sore nipples and yet I’m not pregnant! 😭 I tried tracking with opk thinking I was still ovulating regardless and tracking my bbt I went to the doctors yesterday and did blood work and the test came back negative again. So now doctor wants to start me on provera to start my period. I just feel so defeated since we had been trying for the last two almost 3 months since I ended my period.
