Not sure what's going on!

Jo
I don't know if anyone can help, but I was supposed to get AF on 7/9. Still haven't gotten it but took two tests and both were negative. One was a digital that I took a few days ago and I took it at night. The other was a pink dye and I took it first thing this morning. However all week I've been feeling extremely weird in my stomach...gassy, cramps but not normal period cramps I get. Then this morning I got such intense cramps that lasted like 10 minutes. When I went to pee and wiped it was a little bloody (pinkish). I thought I got my period. But I haven't bled anymore the whole day. Any ideas what could be happening or advice from anyone who may have experienced this? My hubby and I have been TTC for 4 months now. Thanks in advance :)
