So I need to see what you ladies think, on Dec 19th-22nd I was on my period. I had been taking birth control but was put on antibiotics for two weeks so we all know that cancels the b/c out. I just stopped taking b/c in general a week after taking my medicine. 6 days after that I start a period again(Jan 3-5) on but it was a light pink spotting the first day and then medium flow of regular and then back to spotting the third day. On the Jan 3rd I was throwing up and couldn't even keep my sip of water down the next morning I was fine but my back was hurting bad with body aches all over. On the last day I was perfectly fine. Now for the past 3 days my nips have been sore and very tendered. If I didn't had he 3 irregular days on my period calendar I would be two days late for my period but when I add it to it the calendar it pushes my period to Jan 28-30. Do you think my period started again because I stopped taking B/C or possibly implantation bleeding? Should I wait to take a test? What do you ladies think!! 😬
