I have a miscarriage before about 4 months ago. I did not know that I was pregnant until I have a serious cramp and a big red period came out with something grey. A month ago, I had my period on the 13 of feb. Later next month I did not have my period until the last week of March. Along those time, in between (4-5 weeks), I had breast tenderness and my nipple darken and sort of enlarged. Not only did I noticed it, my boyfriend did too. My breast begin to enlarge a bit and I have moved from a A cup to a B cup. But then as I said, I had my period. I did test it out four to five times and all the tests were negative (varies in different day or week). My stomach for months now have feel painful if I apply little pressure to it. And it is always sort of big medium tight although I have not eaten all morning. I'm debating to consult a doctor. Should I?
