The chances of you getting pregnant are high.
You have to wait till your periods are due. There is no way to let you know that you are pregnant before you miss your periods. The earliest way to detect pregnancy
is by getting a blood beta HCG
done after 3 to 4 days of missing your periods.
Relax, be patient, wait for your periods to happen normally. If it does not occur, get the above-mentioned test done and proceed further.
Hope I have been of some help to you.
All the best.
