Could it be?

Kr

I had a mc/cp on Feb 1st, I was 4 weeks. Stopped bleeding around the 7th and bd immediately, ovulated around the 17th. DH and I have been bd’ing every other day. Today is aprox 6 dpo and I should be seeing AF in 8 days. I woke up this morning with the tender breast, lil nauseous, and I’m feeling some light cramping with a lil backache. Today’s my birthday so I’m trying to be optimistic but totally freaked out too like is this our 🌈 🌈 (we had another mc back in November, I was 7wks 3 days so if this is the start of a lil bean it would be our double Rainbow baby). Just not sure if it could happen this quickly bc it took 2 months in between the 1st mc to get a bfp in January... thoughts???
