Day 14 of cycle and have started spotting?? Advice please

Hi ladys really would love some advice. 

Im on my 3rd month of clomid. first 2 months i was on 50 mg and this month i was 100mg day 2 to 6. I had a really late ovulation date last month cycle day 27 and got my period after that. 

I am now on cycle day 14 and started spotting this morning. Is this normal it couldn't be implantation spotting because i haven't even ovulated yet been taking opk since day 10. I am so hoping this month I will get pregnant.. I had a mc in november i got pregnant naturally on that one.. 

So ladys any ideas on why i might be spotting on cycle day 14??
