TTC. Is this infertility ?

So, I was pregnant in July 2019. In August 2019, I found out that I had a Blighten Ovum. I went through the D&C procedure. I bleed for 2 weeks straight. In October 2019, my other half and I were low key trying but nothing happen.. in December 2019, I got my first 2 days of a positive opk and baby danced but sadly I missed it. I got my period in January 2020, I’m here again in February to see if I’m pregnant but my opk testings are making me so confused.

Would you say this is infertility? Keep trying?
