I'm due for AF on Thursday, oct 1
I started getting sick this weekend, sore throat, sinus congestion.. I tried to fight it off without taking meds but yesterday morn I woke up feeling so bad that after I picked up my son from 1/2 day of school.. I went to a local urgent care. Dr told me I had strep and a sinus infection and he was going to prescribe a shot and some antibiotics.
Well, first thing that came to my head was "I may be pregnant" (we been trying for almost a year) so I told the dr and he ordered a pregnancy test
Middle of the day, 11dpo and urine was very diluted! Of coarse it came back negative! Now what if I'm pregnant?? I'm petrified that the shot may hurt a possible pregnancy! 😢
I'm 12dpo today, for my first, I was 14 or 15 dpo before a test showed positive!
