new to the pill

hello!! I just started taking the pill earlier this month & I did my research to make sure it would be effective. I started the day after my period & the pill i’m using says that it is immediately effective if I start within 5 days of the first day of my period. plus I have been RELIGIOUS about taking my pill at the exact same time everyday & I haven’t missed a day. I had been on the pill for about 2 weeks & I took a trip to see my boyfriend & we had unprotected sex 2 times & he finished inside. I kept looking it up & everything I was seeing said that I would be fine & the pill is over 99% effective when taken correctly, but like I said i’m new to the pill & im still uneasy. has anyone had similar experiences & would be able to ease my mind? or should I be worried?
