wondfo positive and FRER negative.... anyone else had this happen?

Liz • 37, trying for baby #2! 5 m/c, 1 d&c. 1 ectopic. One perfect almost 2 year old son who is my world.
To me it looks like a vfl on the wondfo but a bfn on the FRER. Same pee! What should I think? 13 dpo. I told my husband I didn't feel like this month was going to be the one and he disagreed and said he thinks this is the one. I've NEVER wanted him to be right over anything before, lol.
