Confused symptoms

Titi

So I've been ttc my first baby and I've been going to a fertility specialist for over a year and everything seems to be going good. I just finished my second round of clomid. I was having on and off cramps and nausea for 2 weeks. I took a home pregnancy test on Monday morning as the dr requested and it was negative 😞. Yesterday, I woke and noticed when I used the restroom brown with clear discharge and I was cramping. I kept going to the restroom thinking it was my period but nothing only clear/ brown discharge with a little bit of red. After maybe 3 hrs it stopped. But I continued to have cramps and feeling nauseous, dizzy, and a little headache. And I woke up this morning with the same symptoms, cramps, nauseous, dizziness, and a slight headache. Could I be pregnant and tested to early? Or is it my period coming? I've never experienced all these symptoms together before.
