Had protected sex jan 23. he didn't ejaculate and the condom didn't break. We had sex right after my period ended and I ovulated 5-6 days after. In december my period came on the 23rd and in January it came early on the 18th. It's february 20th and I have pms symptoms but no bleeding. Can I be pregnant? Also no other signs of early pregnancy like frequent peeing or drastic changes in discharge
