So confused. Can I be pregnant or is it a period?

I had a period two weeks ago and when I finished, me and my husband have been trying. Today I have shown blood again and can’t understand what this means? Am I spotting? Is it another period or could this be a sign of early pregnancy? I do have slight cramps on my left side of ovaries which I experienced with my first pregnancy/baby. Glow predicted my ovulation dates are from today so I don’t know what’s happening?! I took a test anyway even though it was probably so early to test and it was negative. Any advice or anyone with similar experiences? Pls do share X
