With the combination pill you are taking you cannot expect to conceive as it inhibits ovulation. The side effects you have are part of the usage of the pill. You may get over them in course of time. Pregnancy
can occur while on the pills if the dosages are not taken properly; occasionally there is the pill failure though very less. You can wait for your period and if you do not get it, take a pregnancy test 3-7 days later with a fresh early morning urine sample. You may consult your gynecologist for further support. Take care.
