I am a 29 year old female. I started my period two weeks ago. A few days ago I had a brownish discharge, and now it s a very thick clear (yet slightly brownish) discharge and this is not normal for me, especially since my period only lasts about 7 days. My Lower abdomen is sore and feels like there is a lot of pressure. I did have intercourse with my husband last week and it was painful with a lot of pressure to the point that I had to stop. Today I also now have a sore throat, headache, fatigue, a bit nauseous, and just achy all over. I assume this is just a cold coming on, but I hardly ever get sick. Should I see a doctor or give it another week or so to see if it runs its course?
