ok so i had protected sex within the past couple weeks, however i got my period, a little early. For the first like 4 days it was very very light then about 2 or 3 days it was a little heavier but still light. Also, the past couple days, when I wake up in the morning, I have a complete food aversion and a middle ground between a stomach ache and nasea. Today, I also noticed some very liquidy discharge that was clear and had no smell. Is it likely I'm pregnant?
