Help me ! !

So last night me & my boyfriend had sex, & after we had sex I started to spot. So at the time I’m thinking this is my period, being that my period is expected to come in 2 days ( 1 day now ). I started spotting little streaks of pinkish redish blood so I put a pad on because I’m thinking my period is here. I wake up in the morning & there’s nothing on the pad but regular vaginal fluids. I go to the bathroom & wipe myself & there’s nothing on the tissue. What’s going on here? Could I be pregnant? I have sex all the time, almost everyday. I need some answers please.
