TTC after MC

MC at 6 weeks at the beginning of April. Started TTC again this month. I am 7dpo (according to opk) and yesterday had a pretty large amount of clearish/white creamy looking discharge. It came out so much at a time that it kind of felt like I peed myself lol (sorry if TMI!). I have also been having some dull cramps that come and go, more frequently on the right side than the left. Could this mean Aunt Flo is coming or could it be implantation?
