Possible Strong BFP?!?🌈💕

Ugggh... My worry has my up late and not able to sleep even though I have to work at 730 this morning.. I had a MC two months ago..Which killed me emotionally and mentally.. AF came back right on time 28days later, I just got a vfl on my Bday (Monday) which was beyond wonderful and all I wanted🌈 Its slowly getting slightly darker, BUT I'm Sooo worried that my baby2be will not stay with me and that AF will make her dreadful appearance on Saturday with another MC all over it.. I just need some reassurance and helpful thoughts... Its killing me inside.. I want to be happy and joyful.. but the fear is taking over💔Thanks in advance for any comments💕Here's todays test🌈
