Calculating how many weeks pregnant I am?

I’m pregnant and my last first day menstral was on 5/14.

I took an ovulation tests on 5/27 which I got a 1.2 high LH at 7pm.

So I tested again 22 hours later at 5pm on 5/28 and peaked at 2.95. Me and my husband had intercourse that same night.

I then tested again the next morning at 9am on 5/29 and I got a high LH 1.62.

Then again an hour later 10am and my results were 1.05 high. I stopped testing but we continued to have intercourse on 5/29 and 5/30.

I have included my chart if it helps.

Can you help and explain to me when did I actually ovulate?

How many weeks and days I am?

I don’t have my first appointment for 3 weeks to

ask my midwife. Thank you.
