Helpp need advice.

So I took a test on 1/28 and saw a line (my period was due that day), then took a test on 1/29 but it was fainter. Started spotting on and off for like 2-3 days. Like only a little blood on the pad but no blood clots at all. Stopped spotting today all together. Took a test on 2/1 and I see nothing. My period is now 5 days late and I'm super confused. What is going on? Weve been ttc for 11 months and nothing like this has ever happened. Do I count my spotting as my period or what? 😣😣
