Hi everyone. I have been TTC for over a year, I had one chemical pregnancy last July and since then nothing. I thought my period came early on 18th Feb but last Saturday I received a positive Clearblue test, so I now think it was an implantation bleed. I had heavy bleeding for a day and then very very light for the next three days. I believe it has been four weeks since I ovulated. I got 1-2 weeks positive CB test last Sunday and I have been doing a few cheapie tests over the last week. I haven't received a dark line yet and on the Boots brand ones - even the control like was faint. I.took these two this morning. The pink very very faint one was after five minutes but then it got darker over the next 10mins or so. The blue Boots one had a faint control and test line. I'm worried it's going to be another chemical. What do you think?
