Hoping for a pregnancy!

Hi ladies!

So I have a really good feeling that I might be pregnant. With my first baby, my last period was very light. I don’t know if there’s any correlation but my most recent period was also very light and normally I have a very regular heavy period. Within the last week or so I’ve been a little nauseous and light headed as well. Well today I got some sharp cramping, only lasted a few minutes as I took Tylenol right away. I haven’t taken a test yet because my period is due in about 5-6 days and want the most accurate result. I guess my question is, do symptoms happen that early in pregnancy? I feel like I might be getting my hopes up😔
