Help!

TTC going on 3 years. I’m on round 2 of clomid. My cycle is 40 days and I’m on day 32. I ovulated on day 16, did a progesterone test on day 21 and it was 14.5. I took a pregnancy test yesterday and it was negative. Woke up this morning and I spotted (it was brown). Everyday since I’ve ovulated I’ve had cramping and now this spotting. What do you guys think? Anyone with similar stories? Were you pregnant? I just don’t know if it’s because of clomid or if I pregnant and it’s still early to tell. I’ve never started my period this early or had any symptoms this long before my period. Any thoughts are appreciated. 😊
