Okay so I almost missed a whole week of my period and then today, I see a little blood like the one from the picture. Before this, I have experienced headache, weight gain, acne, cramps, muscle tense, and a big amount of stress due to pregnancy worries. I've taken multiple pregnancy tests including the most accurate "Clear Blue" all gave me negative. I want to know of I should worry about this. And I'm thinking of taking another clear blue to be sure. But in your opinion could this be a light period starting or pregnancy? Ps.I was also getting these sythoms a week before my due period dates as usual.
