What is this? This never happens..

So on June 6th I started spotting and I ovulated the 8th and continued to stop for almost a week. I hadn’t spotted since until this morning. After I had sex I went to the bathroom and I was spotting and my period is supposed to start in 3 days. Me and my fiancé are trying to have a baby and I am just looking so any signs 😂 my boobs have been pretty sore the past couple days but I have recently taken a huge craving to sweet tea and I have NEVER liked sweet tea. Again I guess I’m just looking for signs
