Do you think i could be pregnant ? PLEASE HELP

Key

Hi guys, so I had a period Jan 10-16th & my ovulation week was the 25th-31st. My actual ovulation day was supposed to be Jan 28th, I had sex with my boyfriend on multiple days leading up to the ovulation day. Now my tracker told me my next period was supposed to come this month on Feb 12th, it came early on the 7th. I guess you can say my boyfriend made it come on because of sex earlier that day... so I put my info in the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a>, it analyzes the results and fixed my pass ovulation days from Jan 25-31 to Jan 18-24th. My period is very unusual right now, the first day I barely bled, the second day was heavy, today it is very light as if it was ready to go away. Usually I have a steady medium/heavy flow and a full 7 days..... I see the same thing happening from the first time I got pregnant... SHOULD I TAKE A TEST ????? Please answer !!!
