New to this game 😕

I'm new here...I'm 33 and two months old...stopped my pill (Yasmin) on 10 May, three days later I had a withdrawal bleed, lasted exactly 4 days (the duration of my usual periods) had the usual menstration symptoms...cramps, bloating etc...so felt like a normal period...My gynae told me to use an app and record any first bleeding after stopping pill as a menstration...hence I'm on Glow...has anyone else experienced this and gone on to get pregnant "first time" without letting your cycle settle for a few months? Hope I make sense 😄
