someone please help 😰

So Im nineteen years old and I lost my virginity like a month ago and ever since then me and my bf have been horny bunny rabbits. Not having sex everyday but 3 times a week, 3 rounds. We always used a condom, ALWAYS. I was suppose to get my period this month on the 19 but nothing. It's been a week now and still nothing. I feel a little bloated and gassy🙊 but other than that, nada. Should I be worried? Should I take a pregnancy test? What should I do 😩😩😩😩
