I had sex with mY boyfriend for the first time on the Monday 31st. He has fingered me before so it wasn't that painful and I was slightly drunk but it was consensual. Prior to this my period ended Thursday 27th my periods last 7-8 days before my period I took a pessary for vaginal thrush. Pessarys effect the use of condoms. I used tampons on my period so I was afraid not all the pessary came out of me. So then we have sex on Monday he used a condom and put it on and took it off correctly but my fertile period according to the app started yesterday thursday the 3rd. On the night of Wednesday the 2nd I had brown discharge just a little bit and on Thursday my boyfriend fingered me and afterwards I had a light red discharge. The last couple of days I've been taking excess vitamin c to lower my progesterone can anybody advise  me ?
