Hello girls - please read

Ellen
I am CD24 (normally cycle varies between 28-35). I believe I am DPO8 having got a high strip reading on CD15. My partner and I DTD that day and day after. From DPO3-6 I was feeling dull cramping and side of boobs felt a little sore. I was also sick yesterday but was at a particularly stressful meeting at the time. Last night DPO7 I had very sharp pains to left pelvic area but have woke up this morning with bad cramping like AF due anytime. Boobs feel ok again and really nothing happening downstairs - no spotting or any obvious sign of CM. Think I'm losing hope for BFP 😔
