<s>[INST] Hi, me and my boyfriend have been having unprotected sex mulitple times a day for a week and i was wondering if i could be pregnant. I have the implant in my arm though and we have both been checked at the health clinic so we don't have any STI'S. My last period was two weeks ago if thats any help. [/INST] Hi, I think there is little chance of pregnancy if you are using implant. But even then if your periods delay, do a urine pregnancy test at home.  If positive consult a doctor if you don't want pregnancy. If negative wait for your periods. RegardsDr khushboo </s>
