What could this be?

Hi guys,

Am just a little confused and want some advice/opinions on what this may be. Unsure if it is just normal discharge or if it is a sign of something else. I have been on the pill for about a month now. I got my period 3 weeks ago (it was a week late). I had unprotected sex on both the 3rd and 11th of May, and I’m pretty sure I missed a pill on either both those days or the days after. According to eve (if I wasn’t on the pill) I would be ovulating from around the 30th of April to the 6th of May. I have seen a few mentions of breakthrough ovulation due to missing a pill or two. I have missed pills before and have been okay, but am just wondering if there’s more of a chance due to me being on a new pill. Anyone else experienced this? Its been going on for a few days now. Next period is due in a week (highly doubt it is my period as have never had this before a period and have never had withdrawal bleeding like this)
