Hi, my first time on this but just wanted some advice if possible. So this cycle I was letrozole for 5 days 2.5mg. Doctor said to test 8th dec 16 days post trigger. I had severe back pain on 7th and we tested that day as I knew if I was pregnant then I wouldn't be allowed take painkillers. Came up positive straight away. Again on sunday 8th positive. I must've done 20 tests I was so excited. Anyways yesterday I did the clear blue digital and it said 1-2 weeks perfect. As technically I'm not actually late but ovulated early due to tablets. This morning I woke up and felt different like crampy etc. Did a first response with fmu and it was so faint. I rang my husband (I'm working away) and he met me this evening with a digital to put my mind at ease. It said negative. So now I'm assuming AF is on the way and I've had an early miscarriage / chemical pregnancy. Clinging to hope but has this happened to anyone else and it became positive again or do I just wait it out for AF to arrive. I'm devastated. Been trying for nearly a year for first baby.
