sensitive question and some may not agree with me ...

We lost our little poppy seed at nearly 5 weeks pregnant on 10th Nov ... my hcg levels dropped very quickly and it was all over within 3 days day 1 hcg was 42 day 2 9 day 3 3 .. We asked if we were able to start ttc again immediately they give us the go ahead but recommended we for af first but only for dating purposes I started to track ovulation after the bleeding stopped and on day 6 until day 8 I had positive opk's then neg we dtd both 6th and 8th day I'm now on day 3 dpo counting ovulation as the 8th day just wanting some input as to when to test ? I'm suffering from very sore boobs again which has gone on from ovulation ? x
