Last period feb 8 spotted feb 19 for 5 days. Brownish pink. The 25 dr appoint blood work said will call if pregos. No phone call. 6 days late. Cramps?

Call the office. well since you have already had blood work i would recommend calling them and seeing if they have the results of the tests yet. could be an abnormal cycle, early pregnancy, ovarian cyst, quite a long list of issues.
