I missed three pills in a row the week before christmas and had a really light bleed for 4 days, but i stayed taking my pills as usual. then when my period was due i got none at all and im now late for my next period. did i have implantation bleeding? i have gained about 7 pounds in weight, have food aversions, and i now like foods that i didnt like before, cramping in my tummy that feels like a washing machine, headaches (i never get headaches), and back pain. im always hungry but when i go to eat something i am full after about three or four bites, i get dizzy and am always tired and need the toilet a lot more than usual, no discharge that is abnormal but i will say my labido has increased. i have taken three preg tests after i missed first period but all said negative, my mum had the same experience when she was pregnant three times and even bloods came back negative until she was three months gone.i would love if i was pregnant but if i am not i would like to know whats wrong with me
