Hi I'm 19 years old and me and my boyfriend use protection but normally when we first start we don't then he ends up putting a condom on I was 4 days late on my period when I finally got it the first day was lighter then normal then it was heavy the next day then light the rest my period was 4 days long. Then a day after my period has stopped I got spotting a bright pink blood and then it stopped until I woke up this morning it happened again with normal period colour what could this be ?? This has never happened to me before and I feel sick and bla all the time
