Hi Little Kitten,
I do not know you entire story but let me try to give you some generic information.
I assume that you are trying to get pregnant, your husband has a normal sperm, you have IBS, sonograms are normal (no polycystic ovarian disease; I do not know your age, whether you climaxed or not, previous pregnancies before, deliveries before or any abdominal surgeries (including exploratory).
Some people can feel their ovulation, it is usually more common with women living in a more peaceful environment (does not mean working less). Women working in the big city often are caught in the rat chase and simply do not have the time or peace to be in tune with their bodies signals.
Close to ovulation, hormone levels (oestrogens, FSH, LH) increase this usually makes you feel more aggressive, more amorous
It can also give you headaches and other symptoms but it is supposed to prepare you for conception, pheromones, sexual attractions, sensuality, smell
Of the 10~15 eggs developing within cysts each month in your ovaries (depending on genes, age,
), one breaks the surface of the ovary and falls to be caught by the Fallopian tube on that side (usually). Ovaries are the female equivalent of male testicles and are just about as, I repeat, as sensitive. Remember when your gynecologist touches them!
The ovary that laid the egg may bleed, as the cyst ruptures; it may also become inflamed by the cyst rupture. Sometimes the cyst (cyst is filled with fluid), is larger than usual and releases a lot of fluid. This fluid, especially if bloody, will irritate the inside of your abdomen (peritoneal cavity) and cause you cramping, pain, etc
at times intense enough to make believe that you have a ruptured tube, acute appendix, or some other abdominal drama going on. All this activity, despite being useful for the perpetuation of the specie, is on the other hand irritating for the tissues involved (tubes, uterus, and other structure made of similar muscular cells such as bowels, gallbladder
It is possible that if your bowel walls are already sensitive, the whole process is activated hence the cramping, spasms, and gas.
You produce about 4 liters of gas a day depending on your physique, diet, air swallow, possible infection, bowel activity,
that you usually pass innocently as the day goes on. If you are more physically active, you may not notice gas passing and the shaking of your abdomen may move foodstuff faster along the bowels with less gas production. If you are bedridden like after surgeries, you may hurt pretty bad (cramps). I would not worry about gas per se at ovulation time, understand that all your smooth muscles are stimulated by the effects of hormones, ovarian and pelvic irritation, etc
As icing on the cake, the rupture follicle (cyst) undergoes transformation and starts secreting progesterone, another hormone that would support a possible pregnancy until the pregnancy could take care of itself on its own (placental hormones). This Progesterone, secreted after the ovulation, will somewhat oppose the effects of oestrogens and slow you down as to prepare you for pregnancy, i.e. gain fluid, feeling mellow, at times depressed,
I am almost done. If you did not climax (sometimes, it is hard to climax when you are ovulating because of discomfort) but you were aroused, your genitals may have become engorged without relief called pelvic congestion syndrome, something like blue balls in boys. This may add to your misery.
Finally, ask your gyn or doctor what he means by wrong direction uterus. Roughly, 50% of women have a uterus that is either oriented or bent forward (towards your pubic hair), 25~30% is oriented, bent or tilted posterior, towards your tail bone, and the rest is anywhere in between. If your uterus is very bent, that can theorically give you more cramping at period time (as the uterus has to contract more to push the clots through the bend). Otherwise, you should have a normal fertility regardless of your uterine position.
If you are trying to conceive, I would recommend staying in bed a bit after intercourse (at least 30 min, bedtime is good). That would be a good time to cuddle and perhaps have your husband caress or massage you to pass the time and relax your abdominal muscles. After that, go for it. The sperm cells are attracted by your cervix secretions, they will find the way and there are so many of them, believe me. Even if you took a vaginal douche after sex, you could not wash all of them out. After all, all it takes is one and there are over 60 millions in a average low normal male ejaculation.
Make sure that your thyroid function is normal as pregnancy is demanding on the thyroid.
I am sorry that your IBS makes life miserable for you but that aside, you sound like a normal person to me.
Good luck, Lancelot
If you are trying to get pregnant, and are farting out sperm, then your man is cumming in the wrong hole.
