We have been TTC for 7 months now. We both are starting to get very disheartened with each passing month. This month we decided to BD every day during my fertile window guessed by glow, and used opk to narrow down that window. I had a blazing + opk on the night of the 26th and into the day of the 27th. By the 28th I was back to normal opk results. We also used preseed this month along with putting pillows under my hips after he did his deed and at one point had them under my hips while doing our thing.. see, I believe I would be 6-7 dpo (if im wrong, PLEASE feel free to correct me) ive been having cramps on and off since 4 dpo. The first day of my cramps was so achy, dull, sometimes sharp period like feeling cramps on both sides of my uterus and radiating into the middle. At 5 dpo, the cramps werent as bad, but were more centralized to the middle of my uterus. 6 dpo, (yesterday I think. Could even be 5 dpo. Not 100% sure) they had stopped but my boobs were hurting on the side by my armpits and very itchy nipples (also very red colored nipples). Along with what felt like a UTI, but no itching or burning. Today, I woke up sweating like crazy. To where i actually had soaked hair. And I was soooo motion sickness for like the first hour of being awake, and am still having pain under my armpits but going to my nipples. Lol. This is very unusual for me. Have been sooo tired the last few days that I have been in bed by 9:30 or so, which is VERY unlike me. I even woke up at midnight (after sleeping for only 2 hours) to go pee.. which is also very unusual. This could all be in my head. Buuuut, I never have any type of symptoms or anything around this time. My cycle is pretty regular. Any advice? I feel like im going to get my hopes up again this month.
