Hiya, I am 19 years old. I am on the birth control pill yazmin. On 30/7 I had unprotected sex, i missed two pills after the sex. My period isn't due until the 19/8. This morning (8/8) I woke up to cramping and then went to the toilet to find a brownish/red stuff in my underwear. Its nothing like my normal period. I am currently wearing a tampon. For the last few days I have felt really odd. My stomach is bloated all the time, i constantly need the toilet, i am getting headaches and my breasts are really sore and they feel heavy. I have also been getting light 'period pains' Can I be pregnant? Is this implantation bleeding? i hope so :) I would be so grateful if someone could help me please.
