Help ladies !!

vanessa

So I had miscarriage at 6 weeks back in November, I didn't get a period until Jan 12, I've been doing opk since af stopped, my fertile window starts tommorrow, I haven't detected LH Surge yet, however I just used the ladies room and when I wiped there was a light pinkish discharge?! Is it possible I already ovulated and first response didn't detect it ?!! What's going on !???
