So my period is currently 4 days late and there are no signs of it showing up any time soon. I had a blood test done last week Wednesday and it came back negative. I took a dollar store test after my period being late for 2 days. That also came back negative. The thing is I’ve been having all kinds of early pregnancy symptoms. I spotted 11 dpo and it lasted for 48 hours. Now it’s 18 dpo and nothing. I’ve experienced food aversions, nausea without vomiting, excess salivation. My bra seems to not fit now and a week ago it wasn’t the case. This morning my boobs felt heavy and I had mild tenderness in them. I’ve taken a total of 10 test including 1 blood test since I was feeling the symptoms but they were all before my expected period start date date which was 14 dpo. Should I be concerned.
