First day of my last cycle was on 22 July, after period I had unprotected sex , after that 2 weeks before my period I get all the symptoms of pregnancy and late 4 days , did home test and blood and it came negative , 5 day when I was late I did hard working and on the 6 I started bleeding but unusual from my cycle it's less blood it goes for 2 days and the 3 it much lesser like its finishing , could I still be pregnant if I still have some symptoms nausea, headaches,and breast are really big usually they shrink to a smaller size when my cycle just starts . Going to a doctor today but I'm felling still pregnant , and it's got me worried I had a miscarriage or my hormones are going I crazy ? Thank you
