Welcome to HCM.
On Monday the 1st of August if you do not get your regular period by then, do a urine pregnancy
test with an early morning sample of urine. Home test kits are available in the medical shops. Read the instructions carefully in the leaflet provided and do the test accordingly.
If you see two lines then you can rejoice because you are pregnant. Even a weak positive i.e. light second line is a good sign.
Wish you all the best.
