If I skip an entire period, will I still ovulate at the usual time? Does this effect chances of accidental pregnancy?

I am 11 days late for AF, but the home tests say negative. I know I ovulated though 2 weeks after my last cycle because I went to the fertility dr and had a vag sono done and I was ovulating on my right side. My last cycle was April 6th. I am going crazy not knowing what's going on... My dr put me on clomid to try this cycle, but I haven't even got to use it because it won't come!!! So frustrating not knowing...Has this happened to anyone else?

thank you, it does make sense. I was confused, trying to make sense of my cycle since it went from being like clock work to being very irregular, then on top of that, I became sexually active again, and mainly, i think i over-thought the whole process. thanks again for your response.

Hi Mellonie,

The short answer: Most women do not know when they ovulate, and ovulation can occur at different times in a woman's cycle if her period is irregular or "missed" one cycle. This does not effect a woman's chance of unwanted pregnancy, as there is no "safe" time during the cycle to have unprotected sex, whether or not she is estimating her ovulation date correctly.

The long answer:
Women's bodies do not work like clockwork; our bodies and cycles are constantly interacting and reacting to their surrounding environments, and just as our environments change...so do our cycles.

Timing of ovulation is also not an exact science. Some women ovulate exactly 2 weeks before their period. Some women may ovulate twice in one cycle. There are no perfect measures for ovulation (at home), either, as all of the methods only provide "predictions", "estimates" or it is usually not until after-the-fact that you realize you have probably ovulated. Basal body temperature is the perfect example of realizing after-the-fact that you most likely have ovulated, as it is tracking the trend of the slightest increase in body temperature.

I am not sure how you are tracking your ovulation, or assuming it is occurring about 2 weeks before your menstrual period (if your period is regular, and begins every 28th day, many women can assume they ovulate sometime around the 14th day). If you have not had a menstrual period for this month, you may not have ovulated. I am not sure if you are on birth control (hormonal contraception, such as the pill), but this type of contraceptive prevents ovulation all together.

I hope this all makes sense!
