Help please ! We had our first attempt of IUI in Feb, which unfortunately didn't work. AF arrived Feb 24th (CD 27) my cycles are usually anything from 25-27 days. This month AF was due Tuesday which would have been CD 28 nothing arrived only very slight pink discharge. Nothing yesterday and today my app says I am 2 days late.I'M on CD 30 ... This morning i done a test which was BFN . Now there is more spotting and slight cramps. Any suggestions please , has anyone experienced later cycles after using injections and trigger shots 2 cycles later ? I'd appreciate any stories of experiences and support thank you.
