Girls, I finally did it and took a pregnancy test, and here's what it showed, it was even scary, according to calculations, I am 5 weeks pregnant. I'm afraid to go for an ultrasound, I went to one before and everything ended badly, how to convince myself that everything will be okay. With my first son, I found out I was pregnant at 8 weeks and everything was fine. But now, I'm scared that I won't hear the heartbeat.
