I’m in total shock 😳

We’ve been trying since November last year. Had 3 chemicals since December to May this year. I just had a major back surgery. It was an emergency surgery. My period is normally every 28days but because I’ve been bed bound for over a month and gained 17 pounds I thought my period was gonna be late. We’ve only had intercourse 3 times in the past 2 weeks so I know I didn’t ovulate when I was supposed to with timing it was about a week off. Took 3 test went for a blood draw today Beta came back 52.93 and Progesterone 17.16. I’m thinking I’m around 12 dpo. I’m praying this baby sticks this time I’ve also been on some pretty strong medication since surgery.
