Kennedy β€’ Engaged to my soulmate! Gave birth to our little boy Kayden Kristopher 02.22.2016πŸ‘ΆπŸ’™ Took 13 months of TTC with PCOSπŸ’• TTC baby #2 started August 2018πŸ’–
So I took a clearblue digital weeks estimator and I am so confused !!! When I peed on it it was flashing the hour glass but not at a steady pace and it was also flashing a book with an arrow beside it... What the hell?! Ive watched videos on live pregnancy tests on the CB digital and none of them did this before.. Then once it was time for the result it was flashing between the 2 pictures below .. I can't test again until the morning.. I am 11 days late. And I was so curious of why it was flashing that and i broke it open to find a test strip with a faint blue line on it. Does anyone know whats going on??!!
