My period was 11 days late which is very abnormal for my cycle as it is at most 2 days late. I had light bleeding on the 12th day which was slightly on and off and this lasted for 3 days. After that I just had brown discharge for about 3 days. My periods are usually very heavy and last 7 days. I took multiple pregnancy tests leading up to this point and they were all negative. However, a few days ago I had a very very very faint positive on a cheap stick test and the following morning it was the same (extremely faint) on a clear blue. A few days later I took about 5 tests for a few days and they were all negative. I've had symptoms, but I've had extreme heartburn, bloating more than usual and really nauseas. I could be easily confusing these symptoms. I haven't had sore breasts or anything which I usually do with my period. I've just been feeling unwell and I'm really confused. My doctor told me to wait it out and see if anything else happens. Could I be pregnant?
