Patient: I had my last period on 3rd march although it was a little lighter than normal and lasted 4 days. It is now 22nd march and i think i ovulated 4 days ago. However i have had a little insomnia for nearly 2 weeks now along with daily nausea, lower backache, slightly tender breasts, cramps, frequent urination, frequent headaches, white creamy discharge, mood swings etc…could i have concieved last cycle or this cycle and just have very early symptoms? Pregnancy test was negative this morning as it was an evap.
