QUESTION about implantation bleeding!

okay so, my fiancé and I have been TTC for months. I’m supposed to get my period in 4 days. I ovulated about 10 days ago and tonight after we made love I went to wipe and it was light pink spotting that only was there for about 4 wipes. nothing anymore and it’s been over an hour. does that mean I might be pregnant? does an intercourse push some implantation bleeding or is it something irrelevant from anything to do with being pregnant. I’ve tried asking google all these things but not getting the answers I’m looking for. has anyone else experienced this symptom?!
