Update picture:::Pink spotting 🔴🔴

Joceline

Me and my partner had sex on the 20th which was the last day of my period . Monday I didn't have any spotting,Tuesday I was at school and I felt like wet and weird so I went to the bathroom n I wiped myself and had pink spotting n that was it .i started to be irritated and just emotional, I have headaches , light cramping in my right side and lower back pain . Then Saturday I felt wet again I went to the bathroom and had pink blood again and I put a panty linear by it was all clean . I have experience like clean but milky dish charge it's kinda sticky but that's it do u guys think it's a sign of pregnancy?
