OK so looking for a safe place to talk without judgement me and my boyfriend had unprotected sex on the 13th and ended up splitting up the next day then I had unprotected sex on the 15th with someone new and I took the morning after pill within 20 hours my fertility and period tracker app says I ovulated on the 21st and that day I had pains down one side which suggests it's right and yesterday I had massively sore breasts. Now today I went to the toilet and noticed some brown discharge/blood on my pants and a bit when I wiped! Could i be pregnant or just ovulation or effects from the morning after pill?
