Hello Good Evening,
According to your description you seems to going towards menopause
not to pregnancy
Menopause literally means the "end of monthly cycles" and once 12 months have gone by with no menstrual flow at all.
Menopause is an event that typically (but not always) occurs in women in midlife, during their late 40s or early 50s, and it signals the end of the fertile phase of a woman's life.
However, rather than being defined by the state of the uterus
and the absence of menstrual flow, menopause is more accurately defined as the permanent cessation of the primary functions of the ovaries.
The ripening and release of ova and the release of hormones that cause both the creation of the uterine lining, and the subsequent shedding of the uterine lining (a.k.a. the menses or the period).
Following clues strongly indicated that you are not pregnant but can be going towards menopause:
1. You had last sex with withdrawal method.
2. You got 4 pregnancy tests
negative in last 12 weeks.
3. No any sign of pregnancy
4. You are in the age group of menopause.
But you may go for a USG (ultrasonography
) to rule out any pregnancy which has minimal chances.
