I am still BFing my toddler and periods only came back last month. DH and I DTD sporadically, and avoided what I though would be fertile window last month. AF started on 1st Jan and we DTD around the 8th (can't remember exactly) and then not again until 24 and 25th. I was assuming my cycle would be roughly the same as before I had my DD, so around 31 days so expected AF again on 1st Feb. I started getting cramps on 2nd Feb but nothing else happened until yesterday (5th) when I started to get some spotting but also started feeling sick, the same constant nausea I had with DD which I got even before my BFP. So I did a test yesterday and got a very faint positive. Did another today and it's the same but the spotting has continued. TMI but it's mainly dark brown blood, a bit of red, not enough to fill a panty liner over several hours.
What's going on?! Did I get pregnant on 24th? Is spotting a sign of a chemical and AF on her way or is this implantation bleeding? I'm assuming if I got pregnant on the 8th then BFP would be stronger by now? Highly confused.
