A tiny combination pill containing both estrogen and progestin makes a popular choice for women trying to avoid pregnancy. The additional estrogen and progesterone present in the system thickens the mucus membrane inside the cervix. It stops the sperm from reaching the egg. The artificially synthesized hormones used to prepare this pill replicate the original ones in the body which causes certain effects on the system apart from stopping pregnancy.

Now due to hormonal misbalances caused by the usage of this pill, there are chances of adverse effects on overall health. Some people experience severe headache while using these pills on regular basis. Spotting is another problem observed in women who consumes birth control pills regularly. Sudden mood change is another common side effect of the birth control pills. Tenderness of the breasts is reported by most women after long usage of these combination pills.

Some women even suffer from obesity and some from underweight problems along with nausea. Gallstones, clotting of blood, high blood pressure and liver problems are few severe side effects of these pills. Hence it is advised to consult the doctor before using the birth control pills so that they can suggest the pills with fewer reported side effects.
