I've been taking Gildess fe 1/20 for 2 years and I've noticed my periods becoming so light they're nonexistant. A week ago on (2-28-2016) my boyfriend and I had unprotected sex and he came in me. I was on my last placebo pill and I had not had my period that week. Is it possible that I could have been ovulating? Could I be pregnant? My boyfriend takes citalopram and strattera, those pills are thought to lower aperm count and and cause pre ejaculation. Since that day, I've been experiencing severe upper abdominal pain that comes with sweating and shaking. I don't know what is wrong but I would like the rule out pregnancy.
