so this is my first moth ttc after a loss. I tracked my bbt and did opk. the opk never came back posative but it looks like I had a temp spick right at the end of my period so I'm not sure if that means I ovulated then and that's why I didn't get a posative opk since I hadn't started testing yet. also I started my period today even though it's only been a week since my last one ended. any advice or impute would be helpful. I hope my cycle starts to get more regulate so i can track ovulation AND everything.
