Possible Pregnancy ?🤰🏽

I am 5 months post partum. My cycle returned about 2 months post partum. Ever since they have about 26-28 days, and last 5 days. My last period was on 12-12-18, and according to 2 of my period trackers I should have ovulated somewhere between the 23-25th of December.

I did have sex on the 23th of December which would have been cycle day 12 for me. Then about a week later, on the 30th, which would have been cycle day 19. I had went to the bathroom, and when I wiped I noticed some light spotting, it wasn’t enough to use a pad. It was just on the toilet paper. Then it stopped, and I haven’t seen anything since. I’ve never spotted before my period.

The next day on December 31st, I noticed this dull pain on the left side in my lower abdomen. It was like a pulling/pain feeling. & it lasted until the next morning. Then it stopped & hasn’t came back since.

I’m due for my period in about 2-3 days, so I know that I have to wait it out and see if I get my period. I was just wondering if these symptoms could be pregnant related?

I am not trying for a baby, but we are also not preventing.

Thank you! 😊
