I need answers. Am I pregnant or not?

I was 7 months pregnant when I lost my daughter in September and I recently found out I was pregnant… or so I thought. I felt as if I was pregnant because my hair was starting to fall out and whenever I ate I would get full so fast and I know it sounds weird but it’s the exact same way I felt when I was first pregnant with my daughter. So fast forward to this month, I took a pregnancy test at night on December 11th and it was positive and then I took one the next day in the morning becuase I’ve heard it’s more accurate with your first pee of the day and it was positive. But then on the 17th I started bleeding but as if I was on my period. I had the same symptoms as if I was on my period and everything so I was really confused. I took another pregnancy test the third day of my “period” and it was positive. I stopped completely bleeding on the 22nd and I took a pregnancy test on the 23 and it was negative. Im confused, am I pregnant or not? Did I loose the baby am I just too early to tell? Was I never pregnant? I’ve already made an appointment with an OB and I’m not sure if I should cancel. There’s just so many questions. I need answers. Please let me know if any of you have ever gone through this or if anyone knows what’s going on thank you.
