Watery Period related to pregnancy

Martha

I had started to bleed what looked like my period but I didn't pass any clots and it was lighter and blood was watery and lasted a couple days. I tested negative for pregnancy but I'm still feeling symptoms of pregnancy and symptoms that I don't feel normally during my cycles. I had a faint positive last Saturday and since then had negative tests. I have an appt this Saturday to rule out any issues but any ladies had this and was pregnant? This type of bleeding was very new and different to me.
