I'm very confused about whats going on. I am 5 days late on my period and I've taken a pregnancy test and they come back negative. Today I went to go use the bathroom and I wiped and there was verry very light blood like it was almost like it was there but it wasnt and I am experiencing some cramping as well. I do not know if I am pregnant or just having a late period. This has never happened before even when i got pregnant 6 years ago wit my son. My period has always been on time and regular,Can someone help me understand what going on.
