could i be pregnant?

Tasha

hi first time posting on here so its all new to me...i stopped my pill around 5 weeks ago and had withdrawal bleeding roughly a week after which lasted about 4 days...im due on again around 11th/12th this month...i have been feeling really sick on and off everyday for the last week and have been very bloated and keep getting head aches...obviously i will test if my period doesnt show but do you think i could be pregnant? EDIT: ok was looking for sensible opinions not sarcastic ones...maybe should have added more details...im 25 and have 2 children already...i stopped taking my pill to ttc and have had unprotected sex every other day since stopping the pill (other than the 4 days i was bleeding)
