Hi, I am currently on the pill but I forgot to take it for 3 days and then had unprotected sex whilst I was catching my pill up, my period has now come but I usually get it on Monday and it s now Wednesday and I got it today, the colour switches between being brown and then being a normal red colour but it s very light, a little heavier them just spotting but it s not how it would normally be and when I go to the toilet to pee, it tends to sting. Am I able to get some help to see what s going on?
