Im 19 with suspected endometriosis, I use a tracker to manage periods etc. I ovulated on the 6th June and had unprotected sex the same day. (Dont use any protection) A week later which is day 10 I had pink/light brown bleed/discharge which lasted 3 days. This is a week before my period was due. 4 days before my period was due I took an early detection clear blue pregnancy test and a normal test and there was a faint positive on both. My period due date came and no period so I took the same test again and the same result happened but I took a regular test which was negative. Im now 3/4 days late and only getting negative results. Im planning a doctors appointment for 2 days away which will make me 5/6 days late. I need advice on what to do
