I had unprotected sex the 28th of December, partner finished inside of me… I’m not on birth control a week after had spotting for a couple days light pink and brown, now this week having egg whiteish discharge.. come to find out I’ve been taking vitamins with folic acids in them too. What do y’all think the chances are or me being pregnant also have waves of light cramping as well. Also missed my period in November.
