My usual cicle is 28 days but the last time my period happened 2 days before the date and now 4 days before is there any possibility to be pregnant soon ?
shorting period interval doesnt mean for sure that you are close to be pregnant , as prenancy chance is per period , and not related to the next one 
Does your medical condition need medical attention ?
such as changes in period duration isnt considered as a medical illness as its not accompanied by any other medical symptoms , and its considered almost normal 
General advices to increase your chance of getting pregnant ?
1. make sure to do the sexual intercourse during the ovulation time to increase the chance of getting pregnant 
2. performing sexual intercourse many timeswont effect the quality of male semen , but in the same time ,  performing it in excessive way such as ( 3 times daily ) won't increase the chances of getting pregnant , so just try to perform sexual intercourse in mild range such as once daily and it's enough to get you pregnant 
3. lie down after sexual intercourse for about half an hour , and don't wash your private parts directly after that 
4. take care of your and your partner life style quality , eat healthier food , sleep well , avoid stress and anxiety , do exercise regulary
