Hello
Thanks for trusting us with your health concern.
Condoms have a high failure rate - the rate varies from 3 % to 18 % depending on the method of usage and consistency.
So yes, a chance of pregnancy always exists.
In addition to that, erratic spotting can occur due to - stress, anxiety, emotional turbulence, weight gain or loss, ingestion of hormonal medications, late nights, erratic eating habits, smoking, drinking etc.
Excessive caffeine also can cause spotting.
Ovulatory spotting is also common.
Zoloft also can cause irregular spotting and bleeding.
Conditions such as
hypothyroidism, PCOS (
polycystic ovarian syndrome ) ,
endometrial hyperplasia etc can cause such spotting also.
If the spotting recurs, please see a gynecologist and have a thorough internal evaluation - per vaginum and per speculum.
ALso hormonal assessment - FSH, LH, TSH, Prolactin, OGTT, DHEAS, Free
testosterone,
Lipid profile etc.
A pregnancy test should be taken if you skip your normal period, or it gets replaced with erratic spotting.
All the best.
Take care.
