I removed my IUD June 9th 2016 after 7 years. I started the pill right after it and been consistent except for 2 slip ups. I forgot twice about taking my pill, once in June and once in July. I didn't have sex between 4-7 days later but took my other pill constantly after the misses. I still haven't received my period at all. I spotted (brown) for a day July 5th and had a quick spot (brown) June 30th and that was it. 2 days ago my boob and nipples been very sensitive and tender to touch. Is it possible for me to be pregnant or is this normal.
