I decided to take a pregnancy test before the day I had planned on taking the test. The 20th, 21st, 23rd I took a test first response. My result for my pregnancy test kept coming out positive with a fainted line. The 25th I went to the clinic to confirm my pregnancy but received a negative.. got sad after that. They told me to come back on the first that maybe my hcg is low. Took a home pregnancy test today and my result was a negative. Now I don't even know if I still want to go to the clinic. I'm confused on what's going on. Why is this happening?
