Hallow Dear,
If you had confirmed the day of ovulation on 26th and have had intercourse just three days after the ovulation, you have good chances of
pregnancy. however, any sort of bleeding - pink or brown is not a sign of pregnancy.
Missing a period is the first cardinal symptom of pregnancy. To have a reliable detection of pregnancy, you have following options:
1. Wait for menses to appear. If you miss period, there are good chances that you are pregnant.
2. then wait for about a week and perform pregnancy test on the overnight first morning urine sample. Done earlier, you may get false negative results.
3. Alternatively you may opt for
Beta hCG a test on your blood 10 days after the
unprotected intercourse. Levels above 25 mIU/ ml are diagnostic of pregnancy. if lower than 5 mIU/ml, it denotes no pregnancy.
I hope this will help you.
