What is your bleeding like now - heavy, light, reddish, brownish? Could you tell me the date of your IUI? And on which date you took the pregnancy test?
It is possible that you are having implantation bleeding. Also since the bleeding is very less and more brownish than reddish I would say that there is a very strong chance that you are pregnant.
October 30th was too early for an accurate pregnancy test. But a test now should be able to tell you if you are pregnant.
I hope this helps.
It takes some time for the HCG level in blood to increase to the level when it can be detected in a urine test. Although many manufacturers do claim that their products can show a positive test as early as 10 days after ovulation, these are more likely to produce a false positive or a false negative test.
2 weeks (14 days) after the IUI was too early. An IUI is done just before or on the day of the ovulation. Assuming that you ovulated on the 18th, it will take at least 24 hours for fertilization to occur (which means 19th). It will take another 7-10 days for implantation to occur. Usually, implantation occurs on the 9th day. This will add up to the 28th of October. And it will take another 3-4 days for the level of HCG to show up in the urine. So, even assuming that all events (ovulation, implantation) occured in the earlier part of the range of days concerned, 30th October was still too early for HCG to show up in your urine.
It is unlikely that a cyst can affect the cycle once you have ovulated normally and an IUI has been done. A cyst can affect the ovulation and delay it but once ovulation has ocurred, the corpus luteum formed just after ovulation maintains the hormone levels.
The level of breast pain can be different from women to women as also from pregnancy to pregnancy in the same women. But many women suffer from breast pain in the pre-menstrual period too, so it is not a very reliable indicator of pregnancy.
Bloating and cramping is more likely to be due to your diarrhea than to pregnancy as it it is too early in pregnancy for any gas formation to occur, assuming that you are pregnant.
