5 days late!?!

Sheridan

Ok so I'm super nervous, my husband and I have been TTC for about a month. I was supposed to start on Wednesday the 10th but have yet to start and have had very light cramping for about 2 days with really thick discharge. I don't want to test yet because it might be to early to tell. Can someone please give me advice on when to test and how to stay calm until then? Thanks so much!!
