Hello doctor, i wanted to know that do severe pain during periods affects in getting pregnant or conceiving?

"Severe pain during periods" may occur with endometriosis, which can cause obstruction to Fallopian tubes via adhesion formation. Diagnosis of pelvic endometriosis is done by laparoscopy or just clinical symptoms. A uterine condition of invasion of endometrial tissue (adenomyosis) can cause fertility issues as well. Ask for a referral to a fertility MD for treatment recommendations.
