I can't believe I'm doing this, but I read all the stories in this when I was going crazy, so I thought I'd return the favor for others waiting on their BFPs.
I've never been pregnant. I'm 36 and overweight (I work out and I eat right, but I eat too much, so I'm healthy as hell, just fat). I got my BFP after our first round of IUI using donor sperm (I'm married to a woman). For the last two years, we'd been trying with a friend (turkey baster method) but with no luck. We'd been temping, using ovulation predictor kits, everything we could think of, with no success. We begged, borrowed and stole to get the money to do IUI.
We did FSH and a trigger shot (HCG). I've been on progesterone ever since.
I thought the cramping I had after IUI was partly down to the procedure and partly down to the progesterone, but as it disappeared around day 6-7, it was probably the HCG shot.
So when I started getting exactly the same cramps on 12 dpiui, I wanted to test. I've also had low-level nausea since the IUI and sore boobs (both probably attributable to the progesterone).
Got a BFP on 13 dpiui. Couldn't be more excited.
In summary, my only symptoms were
1-7 dpiui low level nausea (always felt sick, was never going to hurl), sore boobs, cramps, tired
8-11 dpiui actually felt great. Boobs were still a little sore, nausea was marginal, not exhausted.
12 dpiui cramps started again, like before. Not as bad as AF cramps. Boobs got more sore, nausea returned, wiped out!
13 dpiui BFP at 6am.
