is it even a possibility?

So bit of a complicated situation here I recently started taking spirnolactone for high dhea levels which I'm sure is probably the cause here and not pregnancy but I am a little concerned started the spiro on Jan 15th and had unprotected sex several times between then and the 24th of January normally I wouldn't vet my period until about the 26th or 27th of Jan but I had quite a bit of bleeding between the 20th and 24th of Jan enough to be a light period but then got my period again heavier around feb 7th and have had quite a bit of nausea and extreme fatigue not sure of its even a possibility considering I've had a fairly normal period on the 7th advice?
