Sex/periods

Okay so I’ve had sex 4 times this month (January) the first time (Jan/6/19)he used a condom, second time (Jan/12/19) he didn’t cum and he didn’t have a condom on, the third time (Jan/20/19)he had one on and he also had one on the fourth time (Jan/21/19) too, now I’m supposed to get my period on the 26th of January and usually when I’m close to getting my period my nipples are sore buuuut they aren’t sore, so I’m kinda scared, someone please tell me what’s going on before I lose my mind😫
