hi jhw,
I can understand your anguish, I had a slightly similar experience with you. This is the very first cycle we consulted TCM, and my AF just kept delaying... I was worried that TCM kinda "messed up" my system, lengthened my cycle, I directly translated that into meaning I have to wait longer to be pregnant. It was tormenting because I don't know what was going on in my body, but according to the 3 HPTs, I did, I was not pregnant. And even more confusing was my bloatedness and gas, which felt like pre-AF symptoms anyway.
But there really isn't anything I could except wait. I still had meds from my TCM doctor which I was taking daily, so I called and asked what I should do now, my AF is very late but HPT shows BFN. The TCM advised me to come down and see the doc, and the morning before my TCM appt, I had a BFP. Our elation was shortlived tho, because at Wk 6, when there was still no sac, my gynae advised us to prepare for mc.
The most important thing is for you to have confidence. Think about it this way, our body is amazing, and it is able to take care of itself very well, but when we do decide we might need help from doctors, TCM or western, we should give the doctors time to know our bodies and we should trust the doctors and our own bodies, stop imagining the worse, it sounds like you already have enough stress as it is!
Throughout this 2 weeks, the constant visits to the gynae made me realize that visits are very expensive and makes me even more anxious! So mayb just listen to Dr Su, and take things one step at a time, if she tells you nothing is wrong, what do you think a visit to the gynae will tell u?
