Hi I my last period was on 22nd dec 17. On 11 jan i got blood clot with white mucus once. I am trying to concieve. I missed my period in jan 18. Now on 28 jan my vagina was itchy and swollen with thick white cottage cheese like discharge. On 29th jan i took the home preganancy test. It was negative. I am having backpain and headache.. also feeling very bloated and gassy.. i am starving a lot..eating like anything. Could it be pregnancy or something else. Pls guide.
