Hi I came off BC patch in October, had withdrawal bleeding after 3 days and normal period 28days later , this month I'm 8 days late, I'm having hot flashes (my face goes bring red and I boil up) has happened 3 times in past 2 weeks, heartburn past 2 days , high cervix , nauseous, fatigue and so thirsty , especially at night . Tested when af was 2 days late at night time and had drank water before hand ( realized that's not how your supposed to do it after) could I possibly be pregnant or just part of coming off the birth control patch?
