Negative pregnancy test

Yes, it happened with my first pregnancy. I remembered feeling fatigue and nausea. In my head, I was like... Could I be pregnant? I was sexually active so without thinking any further, I bought the pregnancy test. It turns out negative. Sad, yes but I tried to not let it bother me much. Weeks passes, and my period is late but I did not think much! I thought, "I've did the pregnancy test and it's negative. Maybe I overthink and it affect my period." I continued with my life, until I couldn't take it. ALL DAY SICKNESS! I told my mom, and she told me to take a second shot. She was like, "Just take it again, maybe you're not pregnant but you might have other sickness. You don't want that now, do you?" I agreed annnnnnd it's positive! Sometimes pregnancy tests can't detect much when it's too early 😅
