Need help ladies! Should I get a test? So I was admitted to hospital for a spleen problem (which is all fixed now) and they tested my blood 2 weeks ago if I was pregnant and they said it was negative. Last week I felt like my breasts were on fire and they are still sore! I am now 18 dpo today on Monday my period was supposed to start but I had the tiniest bit of light brown blood since then nothing whatsoever! What could this mean?
