If you had unprotected intercourse on 16th August when you had your periods on 3rd August, it corresponds to the 14th day of your menstrual cycle or your ovulation period. It is seen that pregnancy only occurs if intercourse occurs within the 6 days prior to and including ovulation.
The best timing of intercourse in order to conceive is day 10, 12, 14 and 16 (in case of late ovulation) of a 28 day cycle. So chances of pregnancy cannot be ignored. First appearance of pregnancy hormone, HCG, due to implantation occurs 6-12 days after ovulation.
So if you donât want to wait for your periods and test for pregnancy then you can test at 9 or 10 days past ovulation with a sensitive ( 20 - 25 mIU ) pregnancy test. Aimstrip pregnancy test gives good results and can detect 20 mIU of HCG.I sincerely suggest you to do a urine for pregnancy test and if the test comes negative, then please wait for your periods and repeat the test after 1 week of your missed periods date.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
