So my partner and I just tried for our first month and I'm pretty sure I just went through a chemical pregnancy. Two days ago I took a pregnancy test in the morning (Rite Aid Early Test) and it was clearly positive - a faint line, but a line nonetheless; then the next day I took another one in the morning and had the same thing. Then later yesterday I took two others because I noticed my symptoms decreasing (I had really marked breast tenderness and swelling) and they were negative; took an FRER just now and it was negative (after several hours of not peeing so I am pretty sure it is right).
How common are these? Does having one make it more likely I'll have another? Is there anything that can be done to prevent them, and / or does it mean anything about, say, my uterine lining? Is it actually kind of a good sign, because at least we were able to get pregnant on the first try? How long do you have until you get out of the chemical-pregnancy-risk window?
I definitely know that next time around I won't take any tests until the missed period. The only reason I did this time was because I was having such intense breast soreness that I knew something had to be up....
