Could I possibly be pregnant?

Becky

I had unprotected sex the first 2 days after my period ended. It ended January 19th and I had unprotected sex on the 20th and 21st of January. But I've not had a period at all this entire month. Could I possibly be pregnant? Anyone know what I should do? I've taken tests I got negatives & what looks like 2 faint positives.
