I m confused!

So me n my husband were trying for all these 2 years and I got periods with exactly 28 days cycle. This June we tried and then i had period for 4 days. Since then he s been away so we hadn't had sex at all. N now I m late on my period. Could I be pregnant even after period? Can someone be pregnant after period? I don't feel the pregnancy symptoms either. Or I should just wait a few more days n do the urine test at home again?
