Hi there, just wondered if anyone could help, I am on the contraceptive pill but 2 months ago I did miss a pill and was on a course of anti biotics. I had my period that month but was very strange, my periods are normally always on time and medium to heavy flow lasting 5days. This one tho was 2days late only lasted 2 days and was very light watery and pink, not like blood at all. I did take a test which showed up neg, took another one a week later again neg. Therefore thought just a weird period. Although this month again my period was very light and started off brown spotting and again only lasted a day and a half. I have again another neg test, not stressed, not over exercising, no sti/stds. So is this normal... Advise pls :-)
