Hi there, I had my 3rd child 4mths ago, I went on pill a month ago but 4got ive been on antibiotics the whole time, I had sex half way thru my pill pack, then clicked oh no antibiotic, pill is void, so i went straight off the pill 2days after, got my period 3days after sugar tabs for only 2days could i be pregnant & still have period for those 2 days?? & if so can going back on pill harm baby?? when will hgc levels show its been 1in a half weeks since the "accident" Thank you
