problem ttc

[alwayschaos]

this may get slightly confusing so please bare with me.
we have been ttc since april this year had a full period in april. i had some pregnancy signs in early may and thought i may be i tested as i was late but it was neg. then on the 28th may (just under week late) AF arrived but instead of being very heavy and lasting 5 days it was light and lasted 2 days. i re tested but still neg.
we couldnt try after due to use both being away for work so are plannning this time around however again AF arrived on the 28th (friday) its now sunday and im nearly finished. again very light for the few days only filled two pads (sorry). in between this one and the last iv had sore boobs on and of back pain and sometimes i feel sick im pretty sure iv put on weight (dont own scales they depress me).
however the main problems is i use a predicter test kit so i know the dates ect and altho we didnt try last time i still used it and it seems not only has the first day of AF moved so as my fertile time. the reading on the test is really showing up altho im still getting a posative to try its only showing up lte at night ect.

does anyone know why my dates (for AF ect) have suddenly moved? also why im suddenly much lighter and shorter? (not something i thought i would ever complain about) im 24 good health weight no meds ect.

also thankyu to anyone who has mannaged to make sense of what i have written

Have you tested again? Worth ruling out pg before anything else
WRT your 28th May cycle, were you regular before you were TTC? If you are really stressed/ worrying about being pg/getting your period, it can actually delay it by a few days.
You will always ovulate 10-16 days before your period, regardless of the length of your cycle, so that would explain why your fertile phase has moved.
Are you getting + OPKs throughout your cycle? Sorry bit confused.

tested last month and was still neg. docs didnt think worth testing either.
i was having my normal heavy 5day period right up untill april then we started ttc start of feb. i thought it could be stress related its never happened befor when iv been really stressed and im not really stressed at the moment.
i am getting + opks but they seem to be all over the place around 15days but not in the morning but retesting late at night and getting + but then - in the moring lol it is just all over the place iv orderd a new testing kit just in case its the kit. i did have a +opk befor day 10 then after day 16.
im very confussed by it all

That does sound pretty confusing Your LH surge is meant to happen mid afternoon, 2pm ish, so that could be why they are - in the morn, + in the evening?
AFAIK, multiple +OPKS throughout the month could mean multiple hormone surges and indicate that your body is trying to release an egg. The only way to be sure if reasonably sure you're ovulating or not would be to take your waking temperature each morning and chart them. There are online charting sites you can use for free. Fertility Friend is one and they will work out your coverline and whether it looks like you've ovulated for you. If you combine temp taking with observing cm, checking cervix etc, it can help take away some of the confusion and tell you what's going on. OPKs are good in some ways, but they can't actually tell you if you've released the egg, whereas a sustained rise in temperature shows ovulation has occurred.
Maybe do a cheapy pg test, just to be on the safe side!
Hoping things go well for you.
