I really think I’m pregnant!

My boyfriend and I have been trying to get pregnant but I think this may be my month. I’m just a little concerned tho. My period is due this weekend. I had a tiny bit of pink discharge and then it went away. It came back but this time it was brownish. It was so light I didn’t even need to wear a pants liner. So I’ve had discharge on and off for three days and now it’s completely gone. Does this sound normal in early pregnancy? I’m hoping it’s not my period but its waaaay to light and I never spot before my periods. I even had sex because that usually just forces my period to come the days leading up but it didn’t. Thanks In advance! Sorry if this is annoying I’m just really really hoping since I have a fertility issue.

Also, we had sex all throughout my ovulation window.
