No one can predict what their pregnancy journey will look like or how long you'll be trying to conceive (TTC). Every body is different, every cycle is different, and everyone's timing is different. The only universal part of it is that it's an emotional rollercoaster for everyone involved—and it's perfectly captured in this viral TikTok.

User @colette.peri shared her personal journey in a video that will tug at your heartstrings. You'll feel for her disappointment with every negative test, you'll get teary-eyed when she finally gets her "big fat positive," and you'll cheer along with her and her partner's families as they learn the happy news.

First of all, we need to talk about the cats. They're enormous and absolutely adorable and the fact that they were included in many of these video clips is one of the most endearing things of all time.

Also, raise your hand if you always, without fail, cry every time you watch a video of couples finding out they're going to be grandparents for the first time. Whew, is it dusty in here?

According to the NHS, most couples (about 84%) will get pregnant within a year if they have regular sex and don't use contraception. Age does play a role in conception, however. One study found that among couples having regular unprotected sex:

  • aged 19 to 26 – 92% will conceive after 1 year and 98% after 2 years
  • aged 35 to 39 – 82% will conceive after 1 year and 90% after 2 years

There are many reasons you may experience fertility problems, including:

  • hormonal (endocrine) disorders, such as polycystic ovary syndrome (PCOS) and problems with the thyroid or pituitary glands
  • physical disorders like obesity, anorexia nervosa, or excessive exercise
  • disorders of the reproductive system like infections, blocked fallopian tubes, endometriosis, or a low sperm count

While some of these factors affect both women and men, in about 40% of infertile couples, there's a problem with both partners.

My husband and I tried for almost a year before I was diagnosed with PCOS. Once I had my official diagnosis and began taking medication that regulated my menstrual cycle, I was pregnant two months later. So many things are contributing factors during your TTC journey.

No feeling is too big or too small when it comes to TTC, and this viral TikTok nails them all. (P.S. How cute is the egg carton idea? SO CUTE.)
