Question about ovulation.. Please Help!!

Erika🌼
It's been 7 months since I've had the IUD removed and we started ttc right away. My periods have been very regular. I noticed the first three months I could feel when I ovulated but since December I don't get any ovulation pain and my periods have been way lighter. Lasting only 2 days and really light. So light I can't wear a tampon..
My question is... Does it sound like I'm not ovulating? 
I use opk's and do get a positive but never a STRONG positive... I also do get like 1 day of ewcm during my fertile week..
I'm wondering if I should see a doctor..
Anyone in a similar situation?
