I think I may be deluded/going slightly mad so wanted to get some second opinions/advice from the wise ladies on here. I had a FET (day 6 blast) on Tuesday 2nd August (donor eggs). I've had several failed cycles with own eggs and this was my 3rd and final embryo from this cycle. Clinic advised test date was yesterday (based on a blood test) or tomorrow for a urine test. I have FRER tests so yesterday on Tuesday 9th August - negative. I had had some cramping in the days following transfer but then pains continued and felt like period pains (as per every other negative transfer). As I've got spare tests and tested again today, looked negative and then I looked again in a different light and there is the (very) faintest of lines. It is very very light, but definitely there. I'm thinking this line must have appeared after the 3 mins (I wasn't timing but it wasn't long, maybe 5 or 6 mins after I did the test) so it's an 'evap line'?! I'm also thinking that the Tues test was correct as a full week after a 6 day FET with a FRER should be accurate? Even if it is positive today, the line is so faint that it can't be a good sign. I am having period style pains (too late for implantation pains) so I'm pretty sure I'm not pregnant but now the test today has given me the tiniest speck of hope. Anyone had similar or can offer advice? Many thanks in advance.
