Could I still be pregnant if I had multiple negative pregnancy tests?

For a young lady with a history of irregular menses, we will always consider polycystic ovaries as a possible cause. Other possible causes include severe stress, hormonal disorders such as thyroid problems, prolactin producing tumours (prolactin is a hormone necessary for production of breast milk), sudden weight fluctuations, vigorous intensity of exercise, or even a deficient production of the female hormones. Of course, in someone who is sexually active, it is important to exclude pregnancy. The urine pregnancy tests kits are quite sensitive and hence the result is reliable enough.

If you suspect there is a high chance of pregnancy, I would suggest repeating the urine pregnancy test in a week’s time. If it still negative then it is unlikely you are pregnant. Irregular bleeding like what you describe is not uncommon in PCOS even in the absence of pregnancy. I would recommend using contraception if you are sexually active. In addition to preventing pregnancy, contraception like the oral contraceptive pill (OCP) will make your periods regular and light, and prevent endometrial hyperplasia (build up of womb lining) which is very common in PCOS.
