Stressed to the MAXX

Christian
Hey ladies, my husband and I have been trying to get pregnant for 11 months now.  The last two months have been really rough. In January after my period I started to bleed for 10 days, then in February I had no period at all. Hoping that I was pregnant but sad to say I wasn't. :( we have regular sex. So I don't know what's the problem. Help me please
