implantation or period?
so I've been experiencing a couple things and I'm not sure how to feel about it or what it is. on my second week of birth control i missed 3 or 4 pills in a row, I ovulated from jan 12-16 and i had sex from the 14th to the 17th. all 3 days unprotected. on the 19th i had light cramping and light pink spotting followed by a gush of blood i thought it was an early period but it stopped at night , the next day i had nothing and on the 21st i again had light pink spotting followed by a gush of blood. i put on a pad thinking it was for sure my period but the pad was clean it was only when i wiped and a couple hours later i again had nothing. on the 22nd i had light brown spotting only when i wiped.i am expecting my period on feb 2nd and i am still having minor cramps. I'm not extremely nauseous but when i smell certain foods my appetite goes away although i am able to eat it. i am tired and have a weird taste in my mouth but i am not urinating frequently and my breasts are only sore form time to time. could i have experienced implantation bleeding or could it have been an early period for missing the pills?
