Hello, Thanks for sharing your health concern with us. I have gone through your query and would like to offer some suggestions. You had the intercourse during the fertile or ovulation period. Hence, you have high chance of conception. The spotting and discharge you observed is suggestive of expulsion of some altered blood. It does not correspond with ovulation; nor does it mean an implantation bleed. It is likely to be some breakthrough spotting. Your symptoms are not specific to pregnancy. they can be seen during the premenstrual period as well. If you wish to have a clarification earlier than your expected period, please go for the blood test to exclude/confirm pregnancy and plan further management. Hope this helps.
