Late Period After Birth While Breastfeeding

Since you took the morning after pill multiple times within a month may have altered your menstrual cycle and caused a delay in your period. But there is still a possibility of pregnancy even if you have taken the morning after pill. Because emergency contraception is not 100% effective in preventing pregnancy, and repeated use of the pill within a short period of time may decrease its effectiveness.

While it's less likely to conceive right after having your period, it's still possible to become pregnant at any point in your menstrual cycle, including during the days immediately after your period. 
If you've had unprotected intercourse and missed a period, it's important to consider the possibility of pregnancy and take a pregnancy test to confirm.

From the information given, it is highly unlikely you are pregnant. Though, it is better to see the gynecologist for more in-depth evaluation and advise

If your period commenced on August 9th, it is highly unlikely that it is a pregnancy at this point. Usually, waiting for two weeks after intercourse gives the most accurate test result. A home pregnancy test that detects hCG levels can be used for early detection. Keep in mind that stress or other life situations can also change your cycle. Wait a bit longer and then try the test if you need to. 

It's completely normal for periods to be late sometimes even if you have used protection. Common causes could be stress, a change in routine, or hormonal imbalance. If you are concerned, wait a few more days and then take a home pregnancy test. Remember that irregular periods can happen but it is always good to get checked out just in case. 

In women, increased LH in urine is expected during the menstruation period. LH is a hormone that assists in the release of eggs from the ovaries. Following the end of your monthly period, the LH levels might increase as a way of preparing for ovulation. There can be changes in the cervical mucus throughout the cycle. Having lotion-like discharge before getting the sticky one is typical.
