Help, am I 6 weeks or 9 weeks?

Obviously I need a dating scan to sort this out. But has anyone got any way of telling roughly how pregnant I am before a dating scan? What matters is probably "am I 6 weeks or 9 weeks" rather than 6+0 or 6+5 at the moment, because if I'm 9 weeks I need to rearrange screening and ultrasounds.

I've got pregnant very soon after coming off the pill. I don't have any particular pregnancy symptoms, other than now not fitting into my jeans and being a bit headachy and very very slightly nauseous. Not fitting into jeans at 6 weeks seems a bit weird - whereas at 9 it might be plausible.

My cycle was all over the place, and I don't know its length (haven't had a definite period since 1999, have been on the pill since); we've been shagging like rabbits so plenty of opportunity for conception any date since the end of July.

The only "period" I've had since i stopped the pill, could possibly have been a fairly heavy implantation bleed, or a very very light period, lasting 3 days starting 23 August. The only thing I do know is dates of ovulation, based on mittelschmerz (ovary pain) and EWCM, 13 August and 1 September.

Based on a 28-day cycle and a LMP beginning 23 August, I'd be 6+0

Based on ovulation on 1 September, I'd be 6+5

Based on ovulation on 13 August, I'd be 9+3

I've started seeing GP/midwife on the basis of thinking I was 6+0 based on having tested positive on 24 September. Dating scan is set up for 23 October, on the assumption I am 6+0 today - and obviously this wil need rearranging if I'm 9+3 already, because I'll need to sort screening ASAP...

(waiting to hear back from midwife, but might not hear for days...)

Bloating enough to struggle to fit into jeans at 6 weeks is actually unbelievably common and I believe implantation bleeds are more like spotting, not three days worth. I would guess you are six weeks but you never know with babies!

6 weeks tomorrow and haven't been able to fasten my jeans for nearly 2 weeks already!

I would think you are probably around 6 weeks. 23/08 sounds like a period to me. How strong was the line on the test when you tested and at how many weeks after 23/08 did you test? If you had a feint line then that tends to mean about 2 weeks post-ov (but is by no means fool proof). I found jeans uncomfortable from about 5 weeks. The bloating is ridiculous in early pregnancy!

Yep, couldn't fit into my jeans pretty instantaneously. It's likely you would have a withdrawal bleed after stopping the pill before ovulation would kick back in so I think your pregnancy would be around six weeks.

Thanks everyone.

Tested on 24 September after feeling absolutely nothing for weeks, i.e. not feeling remotely premenstrual at all. The line was very definitely positive. I had tested prior to that but don't know the date, and got what looked like a very faint positive - i.e. inconclusive.

Just OOI i was on Cerazette, not the CoC, so I think I wouldn't have had withdrawal bleeding (no ovulatory cycles, no oestrogen, so no buildup of endometrium); and had also very clearly ovulated prior to the bleeding on 23/08 - highly-localized pain only present for a short time, and truly embarrassing quantities of EWCM produced only for about half a day.

Anyway - thanks all for the advice, I shall assume 6 weeks and get on with clothes shopping for next week's holiday, trying to find jeans that don't invite any comments from my mother!
