Pregnant Bellies

Hey everybody, i'm new. My name is tonielle, and im 20 yro. I have been reading this forum for some months now, but this time I really think im pregnant! Do you think you can help me :?:
1. My normal period lasts for about 4-5 days. I had some type of bleeding (that didnt even smell like a normal period, it just smelled like blood) that lasted for 6 days--- day1: spotting. I never ever had spotting before a period, actually, i've never ever had spotting at all. Day2: pinkish show slight cramping, I always get a bit heavier cramps. Day3: deep red/ brown/ light black but not abundant in amount like a normal period. Day4: spotting. Day5: pinkish/ reddish/ brownish color not abundant in amount. Day6: spotting and went away.

2. Ever since then, i've been getting super sensitive nipples that only get more sensitive as the days past. Also my breast are slightly, slightly bigger.

3. Discharge- feels like im leaking a little bit, but I only see it when I wipe.

4. Using the bathroom between every 1-3 hours

5. Headaches- off and on

6. Slight unusual tiredness

7. Slight cramping.

8. When I burp I do these wet burps, and they taste really bad, and I have no idea what that is.

9. Cry at things I normally wouldn't cry at...
I wonder if im making myself feel all these things by constantly being alert for them, I dunno, but some assisstance would be very much appreciated.
What do y'all think?
