So a few weeks ago I had intercourse on my period without protection. Didn’t come in me but I also started birth control back up the Sunday after my period. latley I’ve had some side affects and have had 3 negative test but won’t get my period till next week. I’ve had some headaches, some soreness in breast only at night but not painful, felt like I’ve had a uti & I’ve been very emotional/tired some days! Is this part of my birth control or something else?
