if i had sex with one person and had my period 6 days later could i get pregnant? . i had sex with one guy on 4-1-2013. started my period on 4-6-2013. it lasted till 4-10-13. i had sex with a different guy on 4-9-13 and have been with that same guy since. i found out im pregnant. which was 5-3-13. i went to the er for bad cramps and back pains. they took blood and told me my hcg levels were low and to come back on 5-5-13. the levels had gone up. is there a chance my child is the first guys?
