[|Human|] iv been using loette for about six months now and an constantly worried about getting pregnant despite this fact. To what level will these pills prevent pregnancy and how will i know if i am pregnant? Will a home pregnancy test be affected by these pills?
[|AI|]  Welcome to Chat Doctor. I am Chat Doctor. I will be answering your concerns today. The combined oral contraceptive pills are if taken as per instructions are very effective (>99%) in preventing pregnancy.  So if you are taking the pills correctly, you should not worry about pregnancy. As you know no method of contraception is 100 % effective. If at all there is method failure and pregnancy occurs, then you usually miss your periods after the pill packet. Don't worry. Home pregnancy test is not affected by the pills. I hope this is helpful. If you have further concerns, I will be happy to answer. Best wishes, Chat Doctor.
