Hi mommies/mommies to be, hope all are well.
A brief history: conceived my first child after 3rd attempt and was relatively straightforward. Towards the end she stopped growing so I was induced (took a whole week 
) waters forcefully popped, oxytocin drip... all for it to go to emergency section !
Enjoyed baby one and felt it was time to have another. Month one, nothing. Then 2,3 and 4. By the time six months went by I was seriously worried. I’d read about secondary infertility and was convinced that’s what I had cos we tried; everyday, every other day, legs in air, sleeping with the stuff in me, opk’s, Pre-Seed (waste of money). Always had to wait for little one to sleep so some nights didn’t get down to business TIL midnight with work the next day!
After some time the GP referred us to a fertility clinic. Took ages to be seen! When they saw me they registered my BMI and took blood - all fine. After I had ultrasound and HSG all in one morning. They told me everything looked fine. I couldn’t believe it, I was 2 months short of ttc for a whole year and tests were coming back that there was nothing wrong with me!
Also convinced I had two chemical pregnancies. After HSG my cycle went from 25 days to 31 days! Got my hopes up, took me at least 5 tests (one with faint line) stocked up on folic acid only to be confronted by a 6 day late heavy period. Happened in January 2018 too. So naturally, got my hopes up and got me four tests, stocked up on pregnacare etc... only to have my period a week late.
DD turned 2 in Feb and I was more determined than ever to get pregnant. The pressure alone of everyone asking when I was going to have another, my cousins wife pregnant etc... Also, had worked hard at the gym and lost 4 stone over the course of a year.
So here’s what I did differently:
Felt in the mood on cd4 - went for it but made sure I was wet down there
Did it every other day after that until cd22
Each time making sure I was wet. Sometimes legs in air with bum on pillow otherwise bum under pillow and sleep straight after.
BFP! 6 days after missed period a Clear Blue said 1-2weeks and two lines on rapid response. Both of us were cautious though, almost as if celebrating might bring bad luck.
Week 5. Sore boobs and brown stringy discharge :( told midwife who said it showed on urine sample but not to worry as brown blood meant old blood. Brown stringy discharge continued TIL week 8 when it stopped and seemed to turn yellow. Still had sore boobs, was hungry all the time and felt really sick in the evening/night, waking at 2am thinking I was going to throw up.
I caught a bad cold and had Friday of work. Had shivers, aches and sore throat but knew I could take anything. Got really angry at husband. Not only was he fed up of
Me being ill but he’d invited a friend over to help him mow the garden. He vacuumed but asked me to look and see if anything needed tidying. Everything needed tidying, wasn’t well but wiped work tops, put toys away, cleaned bathroom etc...
Washed up after bbq. Two days later another friend was invited tidied up again, cooked etc... really wore myself out and felt terrible. Emailed work and said I would be off sick for the week.
First sick day. Tried my best to lie on the bed. Then 7 in the eve, I was lying on the bed and felt warm fluid gush come out of my you know where ran to the bathroom and wiped: bright red blood! Told husband, got DD’s jacket on and straight to A and E. Queue for reception alone took 20 mins. Then an hour and a half wait to see a nurse who took blood pressure and and gave a pot to wee in. Back to the waiting room, half an hour wait for doctor who felt my belly and didn’t seem concerned. He said he would ring the hospital for a scan and they would ring me the next morning. Pregnancy still positive according to urine sample.
Hospital called me next morning and said to come in tomorrow. The Tuesday wait was agonising. Worse still, my boobs didn’t hurt anymore - that was my only real symptom! Convinced I had miscarried.
Today my scan was booked for 11:30am, so naturally they saw me at 12:30 bladder was ready to burst. Sonographer tilted screen away just in case the news was grim but she said “I see a heartbeat!” She said it was strong. I cried! No explanation for what had caused the blood. Still have old brown blood now but feeling more confident.
Things to change: stop caring so much on the state of the house.
Quit gym 
Stop stressing.
Hope this helps anyone. I’m nine weeks now and can’t wait for my 12 week scan!
