is this my period

my last period was on the 7 of February. I did two test In March and they came back positive and since then negative. I'm booked in for a blood test on Thursday as I told my doctor I had movement in my stomach and pain on the right side. A few hours ago I started bleeding. I'm really confused is this my period? ( just to say it's not red it's pink and there is also clots. before I started missing periods they used to be really heavy and dark red. one of the tests was dark and then faint)
