if you have a fairly regular 28 day cycle a period due on 25th of may would indicate ovulation was expected to be around 11th of may. the 4th of may is 7 days before that but sperm only live about 4 days (at most 5 days) while swimming around searching for the egg. pregnancy would seem unlikely but it all depends on the regularity of your cycle and your certainty about the dates provided.
sex on 4th may period due on 25th. no symptom in between. heavy/light cramping after 25th to 30th. 9th june no period. i am 18 years. i had protected sex on the 4th of may my period was due on the 25th of may. from 4th to 24th may i didn't get any symptoms. from 25th to 30th of may i experienced heavy to light cramping and legs tingling which are usually my pre-period symptoms. however they soon went away and now its the 9th of june i still didnt get my period. i am really concerned as to whether i am pregnant or just missed my period? please help thank you very much for replying.
