Tww cramping

Manda • Ttc since 2013. Fertility treatments at CNY fertility January 2016. 3 Timed intercourse with letrozole. BFN 1 IUI bfn. IVF 1 transfer BFn 6 frozen. FET#1 2 transfer BFP (2 stuck, 1 split) Triplets BBG
So kinda a rant but also seeing if anyone else had this issue. Im 9dpo on a timed intercourse cycle. The past two days exspecially today I have had cramping. Today enough that I feel almost like my period should be here. Im on progesterone suppositories but never had this the last two cycles. Uhgg.. the things we go through trying to make a baby. Anyone else experience this and have a bfp?
