My period is late...

Pamela

I’m not really sure if it’s just stress or what but I had an unprotected sex with my boyfriend a few weeks ago but I took my bc pills after and the next day too.. but after that, I forgot to take it 3 days in a row. I had a lot of stuff going on so I forgot.. then I started having some spotting, I’m not sure if it’s normal or not since I’ve never used bc pills before I had an ectopic pregnancy.. anyway, I wasn’t feeling so good the following week.. I woke up with a huge migraine which made me throw up and when I was going to the kitchen to get some water, I didn’t like the smell of the food that my stepmom was cooking so I vomited again.. I took multiple tests and all are negative.. Please, I need help since I’m unsure. Thank you in advance and I apologize if my English isn’t really good. I’m kind of bad at explaining in English
