Stress Didn't Prevent This BFP!

My husband and I have been trying for 15 months. I have mild PCOS and cycles that range from 27-35 days. He has slightly low count (9m) and extreme viscosity. We have been just about to go through IUIs. He used Robitussin this month (1 hr before sex only), and BAM! BFP, right in the middle of a horrendously stressful month. I'm also three months post-HSG. We always use Pre-Seed. We were both on South Beach for most of March and April -- first time I ovulated on CD14 in all the time we've been TTC! I wasn't very vigilant about it this month, but I'm back on it now, trying to prevent miscarriage (not sure if that will work).

What was so stressful about this month? Let me count the ways, in chronological order:

CD5: I submit my dissertation

CD7: In-laws and parents both arrive for graduation

CD10: Graduation (that's "Dr. Mommy" to you!)

CD13-15 (ov'd on cd 14): 3 different sets of guests in 3 nights!

CD20/6DPO: Find out my dad has a rare and aggressive cancer

CD21/7DPO: Travel across county, flight cancelled, get 2 hours sleep

CD22-24/8-10DPO: Work and play for 3 days at friend's house on the opposite coast from where I live

CD25-26/11-12 DPO: Present my research at the most important conference in my subfield, which was a super high-pressure situation

CD27 - now (18dpo): Travel to be with my parents as dad undergoes cancer treatment.

The day that dad called to tell me about his cancer, I told my husband that we had to put off infertility treatments, and that even though we timed it really well this month, we were surely a bust because of the stress. Ha.

Symptoms: very few, though I spotted after we had sex 8 DPO and a bit on 9 DPO. Enough for me to use a small tampon. I now wonder whether that was implantation bleeding (I thought I was under so much stress that my period had arrived). I cried for an hour about infertility stuff on 4DPO, but I think it was stress-related. I obviously cried 6DPO when I got dad's news. Otherwise, not moody. I have really vivid dreams anyway, but I screamed out loud in my sleep three times the night of 16 DPO! Finally, starting 17 DPO my nipples have been sore. I had to sneak away from my folks this morning (18 DPO) to get a test.

I'm really praying that this sticks, for so many reasons! If there's anything to take from my story, it's that if you are going through a majorly stressful time, keep on going. And screw anyone that says that stress prevents pregnancy!

The very best of luck to all of us TTC'ers. I don't think I'll relax until I'm 12 weeks -- so worried about miscarrying!
