I took the morning after pill about a week after I was supposed to ovulate according to a <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a>. Seeing that the pill prevents ovulation is there a chance I could be pregnant? I got headaches and terrible cramps about a week after taking the MAP. And I've been constipated ever since. But I have a lot of gas (TMI SORRY) it's been a month since I took it and I'm extremely sleepy all the time. Can it be that my period is due or can I be pregnant? HELP PLEASE!!
