18 and possibly pregnant..(in need of advice)

So ive only been with this guy for a MONTH, im on bc and he hasnt finished inside but im dicey when it comes to bc. I missed maybe 1 pill that week. Im 7 days away from a period and i have a feeling it wont come for another 9 months, if u know what im saying...im having heartburn, frequently peeing and a possible uti which is also a symptom of pregnancy...I just need advice if this test comes out positive...im waiting until i miss the period to take it...i havent even met his family yet 🤦🏻‍♀️ my family will be so disappointed but im sure they will come around to it...neither of us have a license...If i am pregnant I wont be terminating the pregnancy but i might have to consider adoption depending on the circumstances....any advice from some teen moms or more experienced women with many kids?
