I'm sorry if this is tmi but last night I wanted to get it on with my fiance since its been a while and I was sick to my stomach all day yesterday, well I was perfectly fine up until then and then he started going at it with his fingers and I got instantly sick, got a serious headache and got a little lightheaded. felt better after I sat down for a little bit but afterwards I had more of a milky discharge. could this possibly mean pregnancy? I'm sorry if that's kinda dumb to ask lol I have no clue what to look for any more lol 😫
