We are TTC. I was feeling pregnant before my period was due so took a test and got the world's faintest shadow of a line. Then my period came -not spotting, defo a period. It finished 2 or 3 days ago. Felt twinges this morning so did an opk which came up with two lines really fast. Did a PG test to be sure (four actually) and they all came up with clear as day bfps. Is it left over from a chemical? Have I miscarried? If so why are the lines stronger? Is it ectopic? Is it possible to have a period and still be pregnant? My mind is blown.
