A very silly question on peroids and pregnecy. Please adv.?

if I ovulated on September 22nd and had unprotected a few times during my most futile dates then had my period on the 9th-16th (very heavy period) then again on the 22nd-26th (very light period with very sore cramps) If i have conceived last month would I continue my period as normal as it was a few days after when I started my period and miss the next one or would I miss the first one all together. I'm quite confused to weather this is implantation bleeding or just a period. no nasty answers please.
