Recently found out pregnant....

So I just recently found out I’m pregnant and I’ve been thinking about my last period which was January 30-feb 1. Lasting only 3 days when I usually bleed a whole 5 days heavily and during those 3 days I didn’t have heavy bleeding or my normal cramps that are excruciating just some minor tolerable ones. Could it be possible that I conceived in January instead of February? Only thinking about this bc I wouldn’t say Im really “showing” yet but my stomach is more noticeably larger than before. I know I won’t know for sure how far along I am until I go to the doctor which is next week but just would like some opinions if anyone has any or has experienced being further along that they originally thought.

*looking back on my cycle I also realized I had a period in the beginning of January also as well as the 3 days I thought was a period. Are these weeks too close together for the 3 days to have actually been a period? Could that have been around the time implantation bleeding could have occurred? I had posted on here in January a few days before the 3 day “period” and asked if spotting on a panty liner looked like implantation bleeding/spotting but then I had thought I had started what was a period so maybe it really was implantation and the lighter “period” I had was part of that?
