ive read that if u throw up after u take a pill that its like skipping a pill...well on the 19th of jan. i threw up early in the morning & the night before i had sex...on the 19th i forgot to take my pill so one the 20th i took the one i missed & on the 21st i took the one i was suppose to take on the 20th & so on until the 23rd i took two in one day to get caught up & then i had a period. my real period was suppose to start around the 10th of feb. but it hasnt happened yet,but around that time i had a pinkish discharge when i would go to the bathroom but not everytime i would go...& that lasted for about three days,ive read that implantation bleeding happens around the time youre expecting your period. ive also been very very dizzy lately. i took 2 pregnancy tests & both came back negative. could i still be pregnant?
