I had sex around two weeks before Sunday 12/29 and took a pregnancy test and it came out negative. However, my boobs have grown it seems like a cup size and are very sore and I’m so scared that I’m still pregnant somehow. I use birth control pills and condoms and took a pill 12 hours late for the first time, other than that I took them consistently. No condoms have broken as far as I know. I’m about 2 days before my placebo pills and have had bleeding for four days that is very light to be a period but is bright red and seems too heavy to be implantation bleeding? Please help
