If you are so irregular you should see a doctor.
No
http://www.americanpregnancy.org/gettingpregnant/ovulationfaq.htmThis site says that it is possible to ovulate the day after pregnancy and that it is not accurate to say women ovulate 14 days after their period. Every woman is different and they ovulate at different times.
An irregular cycle can be a signal of no ovulation, but genarally speaking, you ovulate every time you have a period.
You have your period a fixed 14 days after you ovulate. So if a woman has her period every 21 days, she ovulates on 21-14=7...the 7th day after the 1st day of her period.
Yes. A woman is fertile pretty much every day of the month. Only 12% of all women ovulate on the same day every month so unless you check every month you don't know when you ovulate. The sperms also live inside for almost a week. A orgasm can also make you ovulate again.
If it is a normal ovary, and the human has normal cycles, it will ovulate every month.
Most women do not ovulate on the same day each month but rather around the same day. There is a very easy way to learn when you ovulate. See related link.
no, did you get your period?
It is not bad to do crunches every day. This is unless you overdo the crunches to the point of pain.
Most women ovulate between day 12 and day 18 of their cycle.
It is bad if you smoke it every day.
You can ovulate the day after an HSG test but it varies depending on the individual. Tests can also delay ovulation.
