over thinking ??? 🤔🤔

19th & it lasted for days , it was pretty regular . A week after , I started getting this brown discharge every time I wiped & I thought nothing of it because I know it could've been old blood . Right after that , I started getting this terrible headache & earache together (it's still going on). I've taken pain meds & even went to the doctor & he told me it was just a sinus infection gone bad , well my prescriptions haven't helped really ... I've been having a little cramping & ive also have had cramps in my inner thighs . I've been craving ANYTHING with peanut butter & I actually went thru a whole jar😂 my period is supposed to come in four days .. am I over thinking ??? What were some of your symptoms for those who've had babies or are pregnant now ??
