Hi ladies I’m so confused, please read....

💗love my girls❤️

I had <a href="https://glowing.com/glow-fertility-program">ivf</a> back in March and unfortunately lost the baby and needed surgical Managment! Got my negative test then 5 weeks later I had a 7 day period on 4th June! Lasted 7 days. My next period is due in 10 days time according to all apps. But the last 3 days I have been getting positive tests! It’s a miracle but how can it show up so early? Maybe I ovulated straight after period?
