Background info: my periods have always been like clockwork, I had the non hormonal copper coil in for 6 years and it was removed in July.
Started TTC for our first child as soon as the coil was removed. I was late for my period that month, took a test, very faint but visible line and then 3/4 days after I started bleeding very heavy and lots of clots and this lasted for three days.
This month pretty much the same has happened, I didn't have a period after my chemical (is this normal?) and at the start of this week I had a very faint positive (I tested because I was having symptoms) but the next day I started bleeding, this time with no clots and I started to bleed before my period was due instead of after and this lasted two days. My period would have been due today. Tested today to make sure and it's a definite "not pregnant" on my clear blue digital test. Weirdly I'm peeing a lot more than usual still and feel sicky.
I've not had my usual 5-6 day period since TTC, both months faint positives and both months bleeding not long after testing.
I'm trying not to feel shit but I can't help but wonder where this journey is taking me 
Has anyone had any experiences with chemicals but successfully conceiving also?
Can I keep trying straight after a chemical? This is what I did last time and it's happened again.
Can only assume both were a chemical pregnancy?
