Okay,so I got Loestrin 24 fe from my doctor a few weeks ago but have not taken it because i am waiting for my period. I had sex and had to take plan B about a week ago. Today I thought i had started my period so I took my first birth control pill, only I dont think I started my period, I think it was just spotting. What do I do? Do i continue with the rest of the birth control pack?
