Alright clomid crew...AF cramps are here 😥

Road2BabyG • 30s, TTC #1
2nd round of clomid and we BD'd every day but one during the 5 day fertile window plus a few days before and after. My cycle was perfect temping and corresponded with opk peak on cd 17.
Was really hoping this would be our month but AF cramps are coming and I took a preg test yesterday and it was a bfn. Still had hope because was only 11 dpo.
 I feel like the 3rd cycle the pressure is on since I my Dr said if it is going to work, it usually does in the first 3 cycles. 
Anyone get their bfp on 3rd clomid cycle??? Anyone else feeling this pressure? (As if TTC isn't hard enough!)
