What do you think? Help.

Can you have normal period like bleeding in early pregnancy? I know this sounds so crazy, but I'm wondering if I might be pregnant. I had sex in my fertile window last month (I'm not trying atm, but it was an accident, I didn't check my app.) I tested the day my period was due and it was negative and then I had what I though was a period on time, but I didn't bleed as heavy or as long as I normally do. I normally start full force heavy, but I spotted before I started and that never happens. Then I bled for 5 days, but the last 2 days were brown spotting only when I wiped. And TMI, but I normally have thicker blood and heavy clots but it was thin watery blood and almost no clots at all. I didn't really think anything of it, but my boobs are really sore now, I'm tired, I'm cramping a bit, and I woke up a bit nauseated. Plus I'm having lots of creamy discharge and no egg white cm like I should have for ovulation this month. I'm still like a week and a half out from what's supposed to be my next period, so it's not AF symptoms. I'm sorry for the book, but please what do you think?
