Confused pls help ☹️

So, we’ve been trying since October. Still no luck! My last period was 1/4 to 1/9 I started drinking Premama 1/10 we baby danced on 1/11 and on 1/15 while using preseed (fertile week was 1/13 through the 19th) I started spotting 1/17 through 1/20 and I don’t start my period until Feb 1st! I’ve never had spotting mid ways through my cycle so, I’m just really wondering why or if anyone else has been through this?
