what the heck is wrong with me???

Ok, so at 5dpo I had spotting for 2 days, went to the doctor for my yearly pap and she said the spotting looked like it could be implantation bleeding.  At 27dpo I took a test and it was positive,day 28 I took the second test from the box and it was negative.   Day 29 I started spotting again and then had light bleeding (not even enough to fill a pad through the whole day) for 2 days and then spotting again.  Day 32 I took another test and it was positive, next day again it was negative!!  Now I'm going crazy so i took another test this afternoon and it was positive!  My guess is tomorrow it will be negative...I'm going crazy!  I was going to give up and go with the negative, but my temp hasn't dropped yet and it's been up for 19 days.  I normally have a 28-32 day cycle so I have no idea what my body is trying to tell me.  I have sore breasts, absolutely no appetite in the morning, the thought of food turns my stomach, and I've been bloated for a week and a half. On top of all of that when my husband and I were intimate (lol) the other night, everything felt different, after my husband looked at me and said "you're pregnant, cause things aren't where they used to be".  This i know is TMI, but if I am pregnant then my cervix would have changed slightly...right??? It's supposed to drop and soften, as far as I know.  I do plan on going for a blood test, but i can't go until Saturday, so i just wanted some opinions.  Anyway, thanks for listening!
