I'd have to say NO. It would be very unlikely as the blood tests are VERY reliabe. Even more so than the preg tests. I'm having the same symptoms, only difference is I'm having all the symptoms of pregnancy. Yet I'm feeling really gassy.
Yes, during the majority of a woman's menstrual cycles, she will ovaulate but not get pregnant.
Menstrual cycles will come to an end as women go through menopause. Women's menstrual cycles will also be stopped if they fall pregnant, while on hormonal birth control, or after a hysterectomy.
I assume that you mean menstrual cycles, and no a person cannot have menstrual cycles while pregnant. It is biologically impossible to ovulate and menstruate while pregnant, the body shuts down the menstrual cycles once you're pregnant.

After a female has reached a certain age to have menstrual cycles, then they can have children.
If you are pregnant you would not menstruate at all, where as if you had been pregnant but experienced abortion or miscarriage then it may take up to three months for menstruation to return while your hormones and menstrual cycles return to normal. Using certain types of menstrual pads won't effect when your period will start, Anion pads contain a negative ion strip which is said to prevent odour and increase energy during menstruation - this is questionable - but it cannot effect your menstrual cycles.
If you have your menstrual cycles you can get pregnant regardless of what else has developed on the outside.
Human females have menstrual cycles so that they can get pregnant, and thus continue the human race! During the menstrual cycle a woman will ovulate and the uterus will prepare itself for the possibility of pregnancy, if pregnancy doesn't occur the uterus lining sheds and the process starts again.
There is always SOME risk. But if you have been taking your pills consistently, at the same time every day for several menstrual cycles, not missing any days, not taking antibiotics during this menstrual cycle, then you have less than a 1.5% chance of becoming pregnant.
No, if a woman has no menstrual cycle then she cannot get pregnant. The menstrual cycle includes ovulation, no ovulation means no pregnancy. This is how hormonal Birth Control such as the combination pill works, it suppresses the menstrual cycles in order to stop ovulation to prevent unintended pregnancy.
No
With advancing age does come shorter menstrual cycles, and furthermore menopause, but that is not the only reason why a woman can have a shorter cycle. There are studies that show that high caffeine intake shortens menstrual cycles. Shorter menstrual cycle indicates a less of a chance of getting pregnant.
Yes, your menstrual cycle will change whenever you've been pregnant - whether that pregnancy ends in abortion, miscarriage, or childbirth. It takes time for your cycles to return to normal after pregnancy, it can take up to a year for the cycles to regulate fully again.
