My last first day of period was Jan 10th. On <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> I ovulated on Jan 27th

Ok so I’m late by 12 days as today I’ve been taking pregnant tests everyday this week all came back negative even digital ones and early detection am I only one? I’m pretty positive I am pregnant but I need guidance I have all the symptoms except morning sickness. I did not have that with my first child. She’s going to be 10 in April. According to app I am exactly 6 weeks today. TIA
