after I had my implant out back in April my periods were around 3-4 days long and have a 29-31 day cycle. Me and my boyfriend have started trying for our first baby last month. my period is currently 16 days late (which made us very hopeful) and I've done 2 tests a week apart but they were both negative. What could be going on for me to be this late? I'm not bloated at all, I'm the skinniest I've been in a while, my boobs don't hurt and I have no cramps so I've got no symptoms giving a sign that I'll be coming on anytime soon as I usually get symptoms for almost 2 weeks before I start.
