Could I be pregnant?

Alix

I had a miscarriage on January 12th and had surgery to remove. However, some of the pregnancy was left behind so I had another surgey on the 9th feb. I think I’ve already ovulated due to symptoms, I always know when I’m fertile. I’m on around day 7DPO We have been having sex without a condom but he’s been pulling out all apart from 1 time. Yesterday I had a bit of light pink discharge? Could it be spotting?
