return to the pill.

So, I was on the pill (Brenda-35ED) from the time I was 14 (bad acne) till I was 21 till I went to Estelle which is the same make up as Brenda, but I got horrible side effect after 3-4 weeks I felt dizzy and nauseas constantly, one day I missed my pill and I felt great and then took my pill the next day I felt sick again. So I went off the pill and I'm now 24, I tried taking Brenda again last year and the very first day I felt the nausea and the day after my period started 2 weeks early. I've now been prescribed a lower dose pill by a different doctor who was confused as to why I was on such a high dose for a person as small as I am 161cm ,44kgs. My concern is getting sick again, I want to be on the pill, It gives me peace of mind even though my partner and I use condoms, breakage is a thing that happens sometime.
