concerned ://

so I had sex on the 15th of November and it was protected. we first did a position where I was on top but it wouldn’t really fit, we slowly tried putting it in and did like 3 strokes and then done. Then we went into the normal basic sex position and it only lasted about 2 minutes. He didn’t cum in me. My period was suppose to come yesterday (November 5th) but it hasn’t. I was having mini cramps for about 2 days now. I usually have sore boobs as my main pms symptom but I don’t have it. I been having headaches for a whole week and yesterday felt kinda sick but I’ve also been bloated but that’s a normal pms symptom for me. I’m just concerned on why I’m late :// I’ve had sex last month on the 28th and was 3 days late and got my period on the 1st so idk if the same thing is happening but maybe that happened due to having sex near my period and it caused it to delay.
