Period symptoms or pregnancy symptoms? Help.

What's the difference between period symptoms and very early pregnancy symptoms? I was ovulating on our wedding night (23rd August) and he's came in me ever since. My periods due around now but I have had the stomach cramps for about 4 or 5 days now as if it's about to start but it hasnt started yet! I normally get spotting for a few days before my period starts And I haven't got that either? My boobs are aching but I get sore boobs before my period anyway so it's really hard to know. Please help me ladies 😁❤️ x
