I have taken 4 pregnancy tests because the 2nd test showed a positive result. However, the other 3 have been negative and the 1 positive test showed positive results after hours, I just happened to see it in the trash. I went to take a test today and I peed on the stick and wiped I had a pink tint on the toilet paper. What does this mean? Could I be pregnant? I didn't have bleeding or anything after that.
