Me and my boyfriend have been trying to have a baby for a year now we have never used protection in the year and a half we have been together.sometimes I will have my period really late and think I'm pregnant... then I have my period and it is very heavy... how can I get pregnant ? Help me

Getting pregnant has everything to do with timing. Do you typically have a 28 day cycle? You need to know when you are ovulation. Ovulation is the only time that pregnancy is possible.

Also, it is important that you NOT have sex every night as this tends to lower sperm count.

Understand that it may not be you that has the problem. Your boyfriend could have a low sperm count or "sluggish" sperm. Since you have been trying for so long it would be safe for you and your boyfriend to be checked out by a fertility specialist.
