Had unprotected sex on july 5 just 1 or 2 days after my period 31 days later i took a first response pregnancy test and it came out negative, am i ok?

Likely okay: You can take another pregnancy test in a few days, but likely negative. If you don't want to be pregnant, consider birth control like oral contraceptive, condoms, or even emergency contraception which you can obtain over the counter. Best of luck!

Low chances: You are least fertile during periods and immediately after periods and most fertile during ovulation which usually falls 14 days after start of menses. If you are negative after 31 days you are not pregnant.

Not pregnant: First response early result pregnancy test is reported to detect HCG up to 6 days prior to your anticipated period. The fact that you have a negative test 29 to 30 days after intercourse should be accurate.
