ANY ANSWERS WOULD BE GREAT

So, I took two pregnancy tests last week. One Wednesday and one Saturday that were both positive and different brands. Then went to the doctor on Tuesday and got a negative pee test and blood test. I've heard that you have to have either recently been pregnant or currently pregnant for a home test to even detect the pregnancy hormone and give you a positive, I've never been pregnant before this time and my doctor didn't bring up the chance of a miscarriage, but then again he didn't really say much. I hadn't missed a period yet so my pregnancy hormone levels would've still been faint and hard to read when I went to the doctor. But now, on Friday, I have some bleeding that looks like it could be my period but isn't as heavy as my first day usually is. Any suggestions as to what's going on? Opinions on if I'm pregnant or not? Really confused. 😔
