I still am in shock 4 days later. I got my BFP on Saturday. DH and I had been trying for 9 months and this past cycle was my first IUI. DH's SA was normal and all my tests came back normal. The only thing that wasn't working correctly was my CM. I hardly had any EWCM and the stuff I did have wasn't very stretchy. DH's little guys just needed a little help to get past my cervix. At first I thought I had missed my window because we didn't BD during my fertile window and the IUI took place the day after O. I got a +OPK Friday morning and ended up Oing that same night. IUI was Saturday morning. Needless to say, we caught the egg! I had no symptoms except implant spotting and still no symptoms.
1-7DPO (1-6DPIUI): No symptoms
8-10DPO (7-9DPIUI): Mild cramping which is unusual for me, but I have had this before and my usual PMS symptoms (tender bbs, acne, moody). Definitely thought I was out. On the night of 10DPO I had a substantial pain on my left side that felt like ovulation pain. It only lasted a minute. I also couldn't stand the feeling of my pants on my abdomen the entire day. I felt so bloated, which I never get as a PMS symptom.
11DPO (10DPIUI): Light brown spotting at 6am on toilet paper. Three wipes and it was gone for the rest of the day. I was worried that this meant my LP was down to 10 days and AF would arrive shortly. I always spot minutes to hours before AF. My usual PMS symptoms.
12DPO (11DPIUI): No more spotting. Cramping subsided. My usual PMS symptoms.
13DPO (12DPIUI): More cramping. My usual PMS symptoms.
14DPO (13DPIUI): AF due. No cramping. My usual PMS symptoms.
15DPO (14DPIUI): Cramping and BFP!
Those of you symptom checking, here's a tip: no pregnancy symptoms will appear until after implantation (6-12DPO). Take that first week to relax and try not to think about every little thing that's going on with your body.
