I had my period last month around the 20 me and my boyfriend trying conceving right after my period and I have really tender swollen breast for the past 2 weeks and now I started cramping and bleeding today what could this mean

Could be an off cycle, could be due to a pregnancy, could be due to a possible miscarriage. Is the bleeding light or heavy? Similar to a period or not as much? Slight cramping or severe?

It was heavy bleeding and severe cramping I feel like I'm never going to be able to get pregnant I've been trying for 4 years now and nothing and than the month that I try getting pegnant my period alays comes early and it very heavy flow chunky blood

Is this the first time you felt that you may have become pregnant? Have you had any miscarriages in the past?

After four years of trying, you may want to consider seeing your doctor for some testing if you haven't already done so. If this has been with the same partner, he should be tested as well.

This last situation may have been a miscarriage, may have been an off cycle. Most early miscarriages are never known.
