I got my period and symptoms from pregnancy I’m 18

Patient: My girlfriend and I are wondering if you could be pregnant and have her period at the same time. Lately we have noticed that she has been having every symptom a pregnant women has. Also, we had sexual intercourse a couple weeks ago and right after we finished she got her period ,or at least that’s what we think, and it was sooner then when she normally gets it. Can you help us.

Symptoms: Cravings, sore breast, nauseous, feet hurt, mood swings, etc.
