Okay so I I had my last period on Dec 27 for about four days, didn't have one in January, last week on tuesday n wed i had light pink spotting and thursday a day of slightly heavier Brown spotting. Then nothing the next day. Then sat one more time of light brown spotting and then nothing since. Could that have been implantation bleeding? My periods are pretty irregular but I'm on day 44 of my cycle, it might have been a light period but it just wasn't consistent for heavy like my usual periods. How long should I wait to take a pregnancy test? So frustrating!
