How does this happen!

Just found out I’m pregnant with baby #2! After trying for over 6 months! We waited 5 years for my 1st. I hadn’t gotten my period since February but I kept testing negative. April 5th my dr prescribed some meds for some small cysts I had and to jump start my period. I took it all and still no period. So just for the heck of it I decided to take a test, then a couple more to be sure lol. I’m not even sure how far along I am. Anyone have similar story?
