hey ladies & gent

just a few questions

can progest pessaries make af late??

and also when do you think i am due for period, i dont know wether i am due today or tomorrow??

here is how it went

got af on the 12th but was after lunch so count d1 as the 13th
clomid cd4-8 which was the 16th-20th
pregnyl injection 23rd
iui on the 25th

so it was 2 weeks ago today that i had iui done, so am i due for af today or tomorrow, normal cycle is 28days???

i have had signs of af coming for around 3-4 days now and usually when i get the signs they usually come within a day or so, but they havent come yet?? i have every sign that there coming just no blood?? i am still using pessaries, on my last one tonight, just wondering weather its cos of pessaries or cos i have my dates wrong???
