Thank you for asking.
If you are never late and you are late this time by 7 days then odds of pregnancy
are more with UTI together as vaginal discharge
and freequent urination explains it.As you had sex in ovulating days so yes looks like a pregnancy.
So here is what you gonna do
If its 33 days since first day of bleeding of last menses have a beta HCG test for pregnancy. If 40 days then Ultrasound will confirm
Now the UTI
use topical clotrimazole
before bed time
for 7 days twice a day
Use topical hypollergenic gels for hygiene
Void after intercourse
good toilet habit
Front to back uni directional wiping after voiding.
Drink cranberry juices 10-12 ounces a day
Increase garlic intake
Take antispasmodics like phloroglucinols for crampings
Start oral progesterones Dydrogesterones thrice a day for first month, then twice for 2nd and then Once continued during pregnancy.
See hte gynecologist for help and stay connected. First trimester is a tough time and these symptoms with perverted diets and vomiting
etc will prevail
