I am so confused... can someone please help

So my boyfriend and I have been TTC for about 10 months.. every month I pray that it's the month... usually my period is right on time... but the last couple months it has been 4-5 days late... but still shows up and last 5 days.... but this month I'm not sure what's going on ....

So here is a recap.. July 10 period started July 14th period ended... fast forward to this month... I started light spotting august 10th &11th (ps.period was late again by 4 days) then on the 12th I think I got my period..... but I'm not sure because it wasn't a constant flow.... it was extremely light.... then it ended the 16th of august... but I am spotting again... the 17th and today the 18th...

I am so confused as to what's happening.... hoping to see if someone can help or see if someone has gone thru this aswell
