me and my hubby are TTC. I got my nexplanon removed 12/28/2015 after having it in for about 8 or 9 months and while having it my period was 3 weeks long.. my last period before this one was 11/12/15 to 12/3/15 and then there is my current period which started 12/18/2015 and at first is was spotty or light bleeding and then it got very heavy for a couple days and then stopped for about 2 days and now I'm bleeding again and it seems to be trying to get heavy again. I have been sleeping more often urinating more going to do #2 more stomach pains, sharp pains abdominal pains, fatigue, weird cravings, eating a lot, Moody etc. what do I do cause I took about 5 pregnancy test over a month ago and they we're negative.
