Could i still be pregnant?

Patient: Could I still be pregnant? Been trying for a baby with my partner for a while now but started to lose hope. We randomly had unprotected sex two days before my expected period. Had very light watery blood the day of and after intercourse only when I wiped but then stopped. Began to feel really sick all day every day, lost appetite for some food, extreme bloating and period came 5 days late. Began with brown blood which then turned into very slight pink mainly red blood however not as heavy as my normal period but still quite a bit of blood. I was devastated as I really did think I was pregnant this time. Could I still be or am I defo not? I only came on today so its been 7 days after intercourse.

Symptoms: Sickness, Slight Tiredness, Loss of apatite, Bloating, Late period
