Question/Confusion

Ci

So two days ago, I use a pregnancy test and just to make sure, I took 10 pregnancy tests. 3 digital came out negative, 1 digital came out positive, and the rest came out positive. However yesterday I spotted pink blood when I went to used the bathroom. I searched up and it’s related to implantation which I’ve never heard before. But this morning, I woke up finding myself having bright red blood on my underwear and I thought maybe it’s because of the implantation. But around 1 pm, I went to used the bathroom and found that there are small pieces of tissue coming out and it’s dark red. So at this point, I’m not sure if I’m pregnant or not. I couldn’t take pictures because I don’t feel comfortable posting it on. But I’m going to have a check up tomorrow morning just to make sure I’m pregnant or not.
