Confused and a little tmi

I'm 23 and currently TTC #2. My husband and I have been TTC for 7 months now and this last month has been confusing. My last period was 4 days of very light spotting. Which is unusual for my periods. This month I am a week late with what I thought was a couple faint positives but last night was a BFN. But I have had light cramping on my right side One day and yesterday I had mild cramps in the front. I never cramp with AF. So I'm really Confused. Plus today I had a lot of ewcm. Enough to think I had started my period til I went to check. Any ideas?
