When you get on BC they say wait up to 3 months and if the pill is not working for you then you should switch to a new one. Is that really true? How long does it take for your body to get use to being on BC? Long story short i am freaking out i started BC again in April and now i am on my 4th pack. I just had my period about 4 days ago that only lasted about 3 days. During that time of being on my period i felt slightly nausea so i worried myself to death and took a pregnancy test that came back negative. Before getting my period i was on antibiotics for about 3 days and i doubled up on protection me & my bf used a condom and plus me being on BC. The condom didn’t break at all. Now all of a sudden yesterday and today i feel slightly nausea again it stays for about an hour or so and goes away. Yesterday i took a digital pregnancy test that came back negative and this morning i took another one since your hCG levels are higher in the morning that came back negative. So idk if my mind is playing tricks on me or it’s just the BC. But I’m worried that i might be pregnant even tho the test that i took is telling me no. Since starting BC again I’m emotional, my anxiety is kinda bad, hungry, tired, fatigue, bloated, breast hurts. My hormones might be out of wack because i recently had an abortion in March and got back on BC in April. I have an appointment with my OBGYN next week to see if i can switch. Should i worry?
