I have irregular periods and am wanting to get pregnant. My last period was in February of this year, and I've not had a period since then and am not pregnant...I was wondering.. Is it possible that I could get pregnant during those months that I've not had a period? For example, say I had my last period in February,...and during the next 4 months I've had intercourse with my husband, is it possible that I could have ovulated during some of those months and get pregnant and have no idea that I am, seeing that I wouldn't be expecting a period because of my irregularity?
