questions

my husband and I have been ttc for 2 years just had the hsg done last week during the 9th day of my cycle on the 22nd .......we had sex the night before 21st than my job sent me out of town (travel nurse) came back on Friday and we my husband and I connected multiple times since Sunday of this well I haven't been able to hold anything down not even water cramps in lower left side and flutters scared to take a test assuming it's to early however I know my lines are completely clear now. is it possible that the procedure pushed his sperm up quicker and fertilization took place
