My cycle is generally 27-31 days and now I'm on CD36. Early last week I had a sever headache that lasted 3 days (not sure why it went away, just glad that it did), extremely tired, mild cramping, a sharp pain every once in awhile low on my left side, clear CM, nausea through out most days (it did go away once I ate though nothing sounded good), going to the bathroom much more often, always hungry (when not nauseous), and tender breasts. Since last Tuesday I've taken 3 HPT's and all were BFN. This week I haven't had any of the same symptoms as last week (except being tired and hungry). Should I wait it out a bit longer or make an appointment with my doctor (I have my annual physical March 24 but would rather not wait that long)
