Had about 5 days of light medium spotting about 3 days before expected period could you be pregnant ive been ttc for months already can anyone answer did anyone experience this and was actually preg?

yes I did in my last pregnany and I thought it was a very, very light period but infact I was pregnant. I had spotting all throughout that pregnany too - so if you are pregnant do not be alarmed if you have more spotting - before this happened to me i had never heard of it before but apparently it is quite common. However now I am trying to get pregnant again and I spot 3-5 days before my period really starts which is frustrating as I dont know if I am just spotting like last time or it is actually a period.
