So, 10 days late AF and negatives in the last week, haven't taken a test in a few days because every time I take it and it's negative I get frustrated. Any recommendations? Think I should give my OB/GYN a call? Just a little hx: my period is usually never late, always get it the 3rd or 4th of every month, its been like that for about 5 years now. I have never in my life skipped a month either. But these negatives are throwing me off and really discouraging!
