Well as you describe you are currently bleeding and your menstrual cycle is regular then chances of pregnancy are negligible.
If this bleeding is not heavy as your regular menstrual period and it's just scanty then it can be implantation bleeding then pregnancy should be ruled out.
However chances are very less.
So you should try again in next cycle.
Start folic acid supplement.
Also eat a nutritious diet.
Monitor your basal body temperature to estimate your ovulation day.
Also you should do sex practices in your fertile days.
Also consult your doctor for further evaluation and management.
