Take some time.

hello madam! u have said that u already had chemical pregnancy last month, and now u have tested for pregnancy, u didnt mention, whether u checked with the pregnancy kits or in the lab ?. also u didnt mention did u take any medications after ur 1st chemical pregnancy ?many of the cases pregnancy kits fail to detect pregnancy, in some cases lab diagnostics also fail to detect pregnancy, as nothing will be seen in ultrasound, inspite of all these failures in detection pregnancy is positive with some women, pregnancy cannot be understood with mood swings, even during regular menses also mood swings are common, only in the advancing weeks can show the result. so i suggest u to consult a gynaecologist and discuss properly what are body changes u r observing in the present period which may give them analyse properly and tell u.

Please keep a vigil on your own physical changes. All the best.
