I'm a bit confused about how my period was last month. So on April 14th I got my period at least I think I did. It wasn't heavy at all nor was it like it normally is. It seemed like it went away within 3 days of having started then it came back so I was on and off for 2 weeks it was very weird it wasn't a normal blood flow. Then 2 weeks later after it really did go away (May 28) I started having pink streaky discharge only for 2 days and a week later which was last week pink streaky discharge with a weird small chunk of I dont know what came out . I thought my period was coming again because I was having mild lower back pain I was also feeling nauseous and have very sore, tender breast which is very rare for me. This morning I took a pregnancy test and it came out positive then I took a second one and and it was negative. I called my doctor right away and he ordered an hcg blood test my results aren't too specific and it just left me more confused. My Results say 22 mlU/ml. Am I pregnant? Could I have miscarried? I have an IUD and 4 years ago I got pregnant with my son while on the IUD. Please help!!
