Hey y'all! I'm new to this app & we've been trying to get pregnant. Well My period is 6 days late. I took a test after I was 3 days late and I got a negative. I'm having all the pregnancy symptoms. I had low hCG levels with my first child. It took forever it felt like to get a positive test. Anyone have any ideas of why it is late?
